        <description><![CDATA[IntroductionMany mesoscale fracture studies focus primarily on reducing error through progressive mesh refinement. However, in heterogeneous materials such as concrete, fracture predictions are influenced not only by numerical discretization but also by the underlying meso- or micro-structure.MethodsIn this paper, an efficient procedure for modeling complex fracture processes in concrete structures is presented, combining virtual and interface elements and exploiting observed statistical ergodicity. Concrete is modeled at the mesoscopic scale as a heterogeneous material comprising a mortar matrix and randomly distributed aggregate inclusions, connected through cohesive mortar-mortar and mortar-aggregate interfaces of differentiated strength. The procedure is demonstrated on the benchmark problem of a notched concrete beam (400 mm × 100 mm, with a 4 mm wide, 30 mm deep eccentric notch) under three-point bending, considering mesh densities of 600, 800, and 1200 elements in the active fracture zone and ensembles of up to 100 stochastic realizations per configuration. Three sources of variability are investigated: mesh geometry with a fixed aggregate arrangement, random aggregate position with a fixed mesh density, and the mortar, aggregate, and interface mechanical properties.ResultsThe results demonstrate that the ensemble-averaged peak load and its standard deviation converge within approximately 75 realizations, and that the variability induced by aggregate placement is approximately three to five times larger than the variability associated with mesh discretization.DiscussionThese findings suggest that, for heterogeneous mesoscale fracture analyses, increasing the number of realizations provides more reliable predictions of the expected structural response than further refining individual meshes.]]></description>

        <description><![CDATA[Sustainable manufacturing has emerged as a critical paradigm for the future of industry, integrating environmental stewardship with operational excellence. Against this backdrop, the rapid evolution of machine learning and deep learning is catalyzing the intelligent transformation of hot rolling production—a sector with substantial energy and material demands. This paper focuses on the core processes of hot rolling and provides a systematic review of machine learning applications for predicting and controlling key quality indicators, including crown, thickness, and width. By fusing multi-source process data with advanced intelligent algorithms, we construct a predictive quality framework tailored to the hot rolling environment, enabling precise monitoring and real-time adjustment of crown deviations, thickness variability, and width fluctuations. Empirical results demonstrate that machine learning approaches effectively capture complex, nonlinear interdependencies between process parameters and product quality, significantly enhancing both production stability and consistency. In addition, we propose a multimodal perception-based framework for early warning and dynamic optimization, facilitating coordinated, real-time parameter adjustments. This integrated strategy not only offers a viable technical pathway for smart manufacturing but also contributes practical insights toward more sustainable and resource-efficient hot rolling operations.]]></description>

        <description><![CDATA[Owing to the abundant supply of sodium and comparable performance to lithium-ion batteries, rechargeable sodium-ion batteries have attracted significant attention for large-scale electric energy-storage applications and smart grids. This study investigated the structural and electrical properties of Ti-doped NaMnO2 using the density functional theory. The exchange-correlation functional in the generalized gradient approximation, as given by the Perdew–Burke–Ernzerhof functional, was used to calculate the total energies. The spin-polarized calculations were performed in sodiated and de-sodiated systems to determine the structural and electronic properties of the 2 × 2× 2 NaMnO2 and NaX(Mn,Ti)O2 supercells. The dopants induced the volume expansion. The lowest conduction band and highest valence band originate primarily from the 3d orbital of the Mn atom and transition metal dopants, which are responsible for electronic conductivity. NaX(Mn, Ti)O2 exhibits a reduced band gap compared to NaMnO2 due to the effect of the Ti dopant. Furthermore, all independent elastic constants for the NaX(Mn, Ti)O2 structures met the mechanical stability requirement of the orthorhombic lattice system, and the formation energy values were found to be negative, suggesting that the structures are stable with the predicted voltage window of between 3.410 and 4.132 V. This study also investigates the thermodynamic properties of a doped system, revealing that the systems remain stable during battery operation, reducing structural damage risk.]]></description>

        <description><![CDATA[This work comprehensively assesses the capabilities of recently emerging foundation models for multimodal image matching and registration in the materials science and engineering (MSE) domain. A distinctive feature in correlative materials microscopy is that the images, which need to be spatially associated, commonly not only have limited mutual information but also distinct length scales. To date, it is largely unknown how foundational multimodal matchers, such as MatchAnything RoMa or ELoFTR, which were trained predominantly with macroscale images from the human environment, generalize to image pairs in such an out-of-domain setting—especially given the pronounced information and field of view disparities in image pairs. To evaluate these models, we use the recently published AmalgaMatch dataset which covers 187 image pairs partitioned into six groups which represent distinct image matching tasks commonly faced in correlative materials microscopy and 19 subsets representing different materials. This dataset with its diverse microscopy modalities and broad range of depicted metals, alloys, and ceramics facilitates evaluation of these models in a rather representative manner. We observe that MatchAnything RoMa, as opposed to the ELoFTR variant, attains satisfactory matching results for many matching tasks and materials represented in this dataset. In contrast, image pairs within the dislocation characterization, slip partitioning and multi-scale groups pose a difficult challenge for these models. These pairs often exhibit limited mutual information and strong field of view mismatch, with field of view ratios reaching down to 2%. We propose inference strategies and workflows which embed a foundation model in an image processing pipeline to increase the matching quality and robustness and ultimately overcome aforementioned challenges inherent to MSE matching tasks.]]></description>

        <description><![CDATA[IntroductionThe optimization of steel materials production for sports equipment manufacturing presents a complex challenge, necessitating the coordinated modeling of material properties, manufacturing constraints, and performance objectives within an integrated optimization framework. Traditional methods often fall short in addressing the high-dimensionality and intricate nature of these factors. This study introduces an innovative digital modeling approach that integrates artificial intelligence and high-throughput computational techniques to overcome these limitations.MethodsThe methodology is centered around the Manifold Guided Optimization Network (MGON), which employs deep learning, manifold learning, and probabilistic modeling to effectively navigate the high-dimensional design space of steel materials. MGON comprises three essential modules: the Counterfactual Constraint Encoder, the Agent Driven Event Planner, and the Probabilistic Uncertainty Filter, facilitating efficient exploration and robust decision-making. The approach incorporates coordinated design strategies, including manifold adaptation scheduling and uncertainty-aware refinement, to dynamically adjust the optimization process and prioritize high-confidence predictions. By formalizing the optimization problem within a mathematical framework and integrating domain-specific constraints, this approach ensures practical applicability in real-world manufacturing scenarios.Results and DiscussionExperimental results demonstrate the potential of the proposed framework to significantly enhance material design, improve production efficiency, and meet stringent performance and cost requirements in sports equipment manufacturing. The findings underscore the transformative impact of advanced computational techniques in optimizing complex manufacturing processes, paving the way for future advancements in the field.]]></description>

        <description><![CDATA[Duplex stainless steels fabricated by Laser Bed Powder Fusion (LPBF) exhibit refined and metastable microstructures that can be particularly sensitive to intermediate-temperature exposure. In this study, the effect of 475 °C thermal aging on the microstructural stability, mechanical performance, fracture behavior, and corrosion response of LPBF-fabricated UNS S32205 duplex stainless steel is systematically investigated. LPBF specimens were solution annealed and subsequently aged at 475 °C for durations ranging from 100 to 1,000 h, followed by detailed microstructural, mechanical, electrochemical, and fractographic characterization. Microstructural analysis indicates progressive ferrite decomposition during aging, leading to embrittlement and deterioration of mechanical and corrosion performance. These transformations result in significant strengthening at intermediate aging times, followed by strength saturation and a severe reduction in tensile ductility at prolonged exposure. One-way ANOVA confirms that aging induces statistically significant changes (p < 0.001) in young’s modulus, yield strength, ultimate tensile strength, and elongation relative to the solution-annealed condition, while effect size analysis demonstrates that aging duration overwhelmingly governs mechanical variability. Canonical discriminant analysis provides a clear multivariate separation of aging conditions and establishes a direct correlation between the combined evolution of mechanical properties and fracture mode transition from ductile dimple rupture to quasi-cleavage and brittle fracture. Electrochemical testing in 3.5 wt% NaCl reveals a progressive deterioration in corrosion resistance with aging, consistent with chromium partitioning and passive film destabilization associated with ferrite spinodal decomposition. The results demonstrate that LPBF-fabricated UNS S32205 exhibits classical 475 °C embrittlement behavior, with enhanced sensitivity arising from its additively manufactured microstructure. This work provides a statistically validated, process-aware framework linking thermal aging to microstructure-property-corrosion degradation, offering critical guidance for the qualification and reliable deployment of LPBF duplex stainless-steel components in thermally exposed service conditions.]]></description>

        <description><![CDATA[This study proposes an intelligent back-calculation framework to estimate multilayer pavement elastic moduli from FWD deflection data under realistic measurement uncertainty. A spectral element method (SEM) model is used to simulate transient FWD responses and generate large-scale datasets. A Transformer regression model is trained to map peak deflection basins to layer moduli, considering four noise scenarios (no error, random, systematic, and combined). Baseline models (BPNN, SVR, and XGBoost) are also evaluated for comparison. The proposed SEM–Transformer framework achieves strong accuracy and robustness, with average R2>0.94 and MAPE < 8% across all noise cases, and shows superior performance for the base course under noisy conditions. The results demonstrate a reliable and efficient data-driven feasibility framework to support pavement structural evaluation and future digital-twin-based pavement management.]]></description>

        <description><![CDATA[IntroductionRecently, the integration of deep learning techniques and computational materials science has catalyzed significant advances in the microstructural analysis of materials, particularly through the lens of multiscale, high-dimensional imaging data. However, conventional models often fall short in capturing the intricate topology and spatial variability that define realistic microstructural patterns, limiting their ability to inform material property predictions, inverse design, and structural synthesis.MethodsTo overcome these challenges, we introduce an innovative deep learning framework designed for microstructural image classification and representation learning, incorporating physical, geometric, and topological constraints directly into the training process. Our method, centered on the structured generative model MorphoTensor, introduces hierarchical tensorial embeddings that retain directionality, anisotropy, and spatial locality—features crucial for realistic material modeling. We further incorporate a Topology-Aware Latent Refinement strategy, which couples persistent homology with differentiable approximations of Betti numbers to enforce topological consistency and augment microstructural diversity. Unlike existing data-driven pipelines, our framework seamlessly integrates statistical encoding, topologicalization, and latent manifold alignment within a unified architecture, ensuring robustness across diverse datasets including phase-field simulations and real microscopy data.Results and DiscussionEmpirical evaluations on benchmark and experimental datasets demonstrate that our method significantly outperforms standard convolutional and autoencoding baselines in accuracy, stability, and generalization. Moreover, our approach aligns closely with the ongoing efforts in the broader computational materials and mechanics communities to build interpretable, physically informed, and adaptable deep learning systems. These contributions illustrate the potential of structured deep generative modeling as a foundational tool for advancing intelligent microstructure analysis and design in materials informatics.]]></description>

        <description><![CDATA[The size and gradation of aggregates strongly influence the performance of asphalt concrete. They directly affect the deformation characteristics and fatigue resistance of asphalt concrete pavements. During production, transportation, and storage, granular aggregates are accumulated in bulk. When allowed to settle naturally, gradation segregation may occur. This leads to an uneven spatial distribution of coarse and fine particles. As a result, traditional screening methods cannot achieve rapid and accurate gradation detection. This paper proposes an intelligent identification method for aggregate heap gradation based on binocular machine vision and deep learning. We use a binocular stereoscopic vision system to reconstruct the three-dimensional model of the heap. The actual height of the heap is determined by acquiring a disparity map using Semi-Global Block Matching stereoscopic matching. Top-view images of the conical heap are captured, and deep learning algorithms segment aggregate particles and quantify the area proportion of coarse particles on the surface. By analyzing the concentration gradient of coarse particles in radial zones, we develop a multiple linear regression model linking surface distribution to the overall coarse aggregate gradation. Experimental results show that the proposed method is much more efficient than the manual screening method in the laboratory environment. The average relative error for aggregate pile height from three-dimensional reconstruction is less than 5%. The coefficient of determination for the prediction model of aggregate gradation is 0.970. This study thus provides a low-cost, high-efficiency approach for detecting aggregate gradation.]]></description>

        <description><![CDATA[To address the issues of traditional backfill material mix design relying on experience and low efficiency, this study proposes a physics-informed neural network (PINN)–transformer method that integrates physical constraints. A dual-task prediction framework is constructed considering material strength and slump, embedding strength development monotonicity, convexity constraints, and slump rheological principles into model training to improve the accuracy and physical reasonableness of the prediction results. Experimental results show that this method improves the mean absolute error (MAE) metric by 6.0% compared to the transformer in strength prediction and improves the slump prediction MAE metric by 6.5%. A multi-objective mix optimization system is established based on prediction results and economic analysis, proposing three optimization strategies adapted to different engineering requirements. This method breaks through the limitations of traditional empirical design and provides efficient and reliable technical support for scientific mix design and engineering decision-making regarding mine backfill materials.]]></description>

        <description><![CDATA[With the global increase in energy demand and environmental awareness, it has become crucial to develop new types of energy materials that are efficient, stable and environmentally friendly. Lead-free perovskite materials have garnered attention due to their unique crystal structure (ABX3) and photoelectric properties, particularly demonstrating great potential for applications such as photovoltaics, photodetectors, catalysis, and display lighting. However, the lead toxicity of traditional lead-containing perovskite materials limits their large-scale commercialization. Therefore, the research on stable and non-toxic lead-free perovskite materials has become a current hot topic in scientific research. In recent years, artificial intelligence technology has brought about a transformation in the study of perovskite materials. This review focuses on the application of AI in lead-free perovskite research, including data collection, preprocessing, feature extraction, model training and prediction, reverse design and experimental verification. This paper aims to leverage AI technologies to drive data-informed and inverse-designed discovery processes, thereby improving the efficiency and success rate of lead-free perovskite materials screening, development, and performance optimization.]]></description>

        <description><![CDATA[In this study, we propose a novel defect localization method that integrates the graph neural network (GNN) with the finite element method (FEM) to estimate the three-dimensional location of defects in perforated carbon-fiber-reinforced plastic (CFRP) interstage structures. Specifically, the model uses distributions of the sum of principal stresses on the surface (DSPSS) to predict the three-dimensional location of defects. FEM is employed to simulate tensile loading conditions and generate stress distribution data using Teflon sheets to represent predefined delaminations. These distributions serve as inputs to the graph attention network (GAT), which classifies defect positions into 19 categories. The proposed method achieved a macro-averaged F1-score of 61% and accurately predicted both the insertion layers and planar positions of defects.]]></description>

        <description><![CDATA[IntroductionAccurate prediction of flow stress during the hot deformation of 7075 aluminum alloy is essential yet challenging, as conventional constitutive models are often inaccurate and artificial neural network (ANN) approaches are computationally complex.MethodsHot compression experiments on as-rolled 7,075 aluminum alloy were carried out using a TA DIL805D thermal simulator over a temperature range of 573–733 K and strain rates between 0.001 and 1.0 s-1. The resulting experimental data were subsequently used to train four machine learning models—decision tree, random forest, support vector machine, and XGBoost—for predicting the flow stress of annealed 7,075 aluminum alloy. Model performance was evaluated through residual analysis and several statistical indicators, including mean absolute error (MAE), mean squared error (MSE), average absolute relative error (AARE), correlation coefficient (R), and coefficient of determination (R2).ResultsThe results demonstrate that, compared with previously reported artificial neural network (ANN) models, these four machine learning approaches achieve comparable predictive accuracy (up to 99.9%).DiscussionWhile offering a simpler and more efficient model construction process.]]></description>

        <description><![CDATA[Wood, a widely distributed renewable resource, plays a vital role in accelerating urbanisation. However, wood grain defects pose significant safety hazards. Detecting these defects is challenging due to low image clarity and contrast, as well as similar colours between defective and non-defective regions. We propose a novel detection network, EPANet, which leverages edge priori enhancement to address these challenges. EPANet includes a global edge priori enhancement module to capture key contextual information and a local edge priori enhancement module to highlight important edge features. This dual approach improves the network’s focus on defect regions and enhances detection accuracy. On publicly available datasets, EPANet achieved an AP50 of 0.869 for single-grain defects and 0.914 for multiple-grain defects, representing at least a 16.8% improvement over baseline methods. Our algorithm outperformed existing texture defect detection algorithms, demonstrating superior robustness in handling multiple noises. EPANet significantly enhances the detection of wood grain defects, ensuring safer and more efficient wood production. The proposed edge priori aggregation modules contribute to the network’s superior performance, making it a valuable tool for real-time wood defect detection.]]></description>

        <description><![CDATA[Magnesium (Mg) alloys show promise for lightweight structural and biomedical applications, but they face challenges such as poor corrosion resistance and complex deformation behavior. This systematic review explores how Artificial Intelligence (AI), Machine Learning (ML), and Deep Learning (DL) address these limitations. These techniques enable the fast and accurate prediction and optimization of material properties, thereby reducing experimental effort and accelerating the design of high-performance Mg alloys. A multi-database validation approach using Scopus and Web of Science ensured methodological robustness when searching for AI, ML, and DL in Mg alloys. A comparative analysis of author keywords, index keywords, sources, authors, and countries confirmed strong thematic consistency between databases, thereby enhancing the credibility of the cluster-based bibliometric analysis. The PRISMA framework was used to ensure the structured literature search, eligibility assessment, and documentation of the selection process. 185 peer-reviewed articles (2015–2025) were analyzed and organized into seven refined thematic clusters: ‘mechanical behavior modeling using neural networks’, ‘AI-driven alloy design and compositional optimization’, ‘atomic-scale modeling and physics-guided learning’, ‘AI applications in welding and thermomechanical processing’, ‘biomaterials and microstructural optimization’, ‘corrosion modeling and degradation prediction’, ‘data-driven design and integrated optimization frameworks’. The review highlights the extensive application of models, including Artificial Neural Networks, Convolutional Neural Networks, and hybrid frameworks that combine ML with optimization algorithms or physical simulations. These approaches enhance predictions on mechanical properties, microstructural changes, corrosion behavior, and processing results of Mg alloys. The study also discusses cross-cutting themes such as simulation speed-up metrics, model interpretability across domains, and limitations in dataset coverage. Findings indicate AI-based methods can expedite alloy design and performance optimization; however, challenges remain in data accessibility, model interpretability, and experimental validation. The study concludes that integrating physics-informed ML models, using multimodal data, and employing inverse design will be crucial for advancing the intelligent development of high-performance Mg alloys for sustainable engineering applications.]]></description>

        <description><![CDATA[Intermetallic titanium aluminides are interesting for aerospace and automotive applications due to their superior high-temperature mechanical properties. In particular, γ-TiAl-based alloys containing 5–10 at.% Niobium (Nb) have attracted significant attention. Molecular dynamics (MD) simulations can elucidate and optimize these materials, provided that accurate interatomic potentials are available. In this work, we compare active and passive machine learning approaches for developing TiAlNb interatomic potentials using both deep potential molecular dynamics (DeePMD) and the moment tensor potential (MTP) methods. Our comprehensive evaluation encompasses elastic constants, equilibrium volume, lattice parameters, and finite-temperature behavior, as well as simulated tension tests and generalized stacking fault energy calculations to assess the impact of Nb on the thermo-mechanical properties of γ-TiAl and α2-Ti3Al phases. Active learning consistently outperformed passive learning for both methods while requiring only a fraction of the training samples. Notably, active learning with DeePMD yielded a single potential capable of predicting the properties of both phases, whereas MTP exhibited limitations that necessitated separate training for each phase. Although active learning potentials excelled in predicting high-temperature behavior, their room-temperature property predictions were less accurate due to a sample selection bias toward higher temperatures. Overall, our thermomechanical analysis demonstrates that Nb incorporation enhances ductility while simultaneously reducing strength.]]></description>

        <description><![CDATA[IntroductionIn the field of materials science, the prediction of material properties plays a critical role in designing new materials and optimizing existing ones. Traditional experimental approaches, while effective, are resource-intensive and time-consuming, often requiring extensive trial-and-error methods. To address these limitations, the integration of digital technologies, such as computational modeling and machine learning (ML), has become increasingly important.MethodsThis paper proposes a hybrid multiscale modeling framework that integrates molecular dynamics (MD) simulations, finite element methods (FEM) from continuum mechanics, and supervised ML algorithms—including deep neural networks and gradient boosting regressors—to enable accurate and efficient prediction of material properties across scales. The method integrates MD simulations for atomic-level interactions using Lennard-Jones and embedded-atom method (EAM) potentials, FEM-based continuum mechanics for stress-strain analysis and thermal response evaluation, and ML techniques trained on multiscale descriptors (e.g., bond energy, stress tensor, coordination number) to model nonlinear property relations and accelerate design iteration. Hierarchical feature fusion modules combine low-level atomistic descriptors with high-level continuum features.ResultsBenchmark evaluations show improved performance in predicting elastic modulus, thermal conductivity, and phase transition temperature across five material classes. Our experimental results demonstrate that this integrated methodology outperforms conventional methods in both prediction speed and accuracy, particularly in complex or multicomponent systems.DiscussionThis approach significantly reduces computational costs and accelerates material design workflows by predicting properties with high precision across a wide range of materials. It aligns with current trends in leveraging advanced digital technologies to enhance materials discovery, offering a robust, scalable, and extensible framework for the optimization and design of advanced materials in various industrial, technological, and scientific applications.]]></description>
