This important research area focuses on how structures and materials can be best designed to absorb energy in a controllable and predictable manner. Advanced structures with optimized geometrical properties and material selections could outperform conventional uniform structures in terms of energy absorption capacity. Advanced geometrical configuration could reduce the initial peak load as well as increase the mean crushing load, which provides the structure the possibility to collapse in a more controlled manner and have a remarkable energy-absorbing efficiency. The materials have wide-challenging properties such as viscoelastic behavior, deformation behavior, and damage initiation and propagation mechanisms, which are important in assessing the mechanical properties of the structure. The advanced materials could be used in multi-purpose applications with their flexibility, energy absorption, and the possibility of utilizing new fabrication methods such as 3D-4D printing.
Advanced materials and structures have appealed tremendous interest for their advantages in a range of engineering problems in fulfilling requirements in safety, environment, affordability, and cost over recent decades. As an effective approach, new systems of advanced materials and structures intend to exploit the benefits and characteristics of different materials to maximize their practical characteristics in lightweight structures, thereby improving their corresponding material efficiency. The common shortcoming, brittleness, higher material cost, sensitivity to the environment, etc., could be mitigated to a certain extend by means of new types of advanced materials and optimized structural topology, which enhances overall performance in a synergetic method and demonstrates substantial competence of balancing mechanical performance and material cost while attaining a primary goal of mechanical property modification and specific energy absorption.
The Mechanical properties of advanced materials and structures for energy absorption are related to the material-structural response to quasi-static, impact, blast, and high-rate loadings. The relevant areas include the following topics, but are not limited to:
• Fiber reinforced composite with multi-functions for energy absorption
• Mechanical properties of metamaterials with advanced structures under quasi-static loading (Negative poison ratio, origami stricture, etc.)
• Dynamic behavior and failure of materials including plasticity and fracture
• Mechanical performance of non-Newtonian material under impact loading
• Mechanical properties of soft materials, such as aerogel, etc., under quasi-static and impact loadings
• Behavior and failure of structures and materials under impact and blast loading
• Systems for protection and absorption of impact and blast loading
• Structural crashworthiness
• Additive manufacturing structures
