About this Research Topic
Smart Materials, such as Magnetorheological (MR) materials, have found a variety of applications in engine mounts and clutch systems in the automotive industry, shock absorbing safety devices for cockpit seats in aerospace, shock absorption for prosthetic-leg movement in biomedical engineering, vibration comfort control for semi-active suspension seats in marine engineering and so forth. Thanks to their excellent rheological properties, MR systems can be controlled by an external magnetic field strength to maintain optimal working conditions in response to environmental changes. In the past decades numerous studies have been undertaken on the development of new MR materials, microscopic and macroscopic modelling, fabrication and industrial applications. However, the research on operation condition monitoring of these smart systems are relatively rare. The safety and reliability of the smart systems are of great importance for benign development and long-term applications of MR materials.
With breakthroughs in sensor technology, it is possible to measure various physical signals to investigate the dynamics and monitor the health conditions of smart systems; for example, piezoelectric sensors, industrial CT, and high speed CCD. More importantly, modern numerical simulation technology is now able to produce comparable accuracy to the experimental or real measurements in modelling very complex dynamic systems. The cutting-edge digital twins technique is able to integrate advanced sensing and numerical simulation technologies together to understand the actual performances of smart systems in support from real and virtual measurements. As a result, more advanced non-destructive monitoring paradigm can be developed to perform just-in-time maintenance decisions.
Driven by such motivation, this Research Topic is intended to offer insights into modelling and non-destructive monitoring of smart systems. Emerging modelling techniques are expected to visualize the undergoing physics inside the smart systems or to discover important parameters to perform non-destructive evaluation.
