The concept of the “virtual test” methodology for complex material systems is gaining momentum within the advanced materials research community. The best form of this method, taking advantage of major advances in computational methods and ultra-high resolution experimental characterization of progressive damage processes, advocates a comprehensive multi-scale approach that utilizes a system of hierarchical models, engineering tests, and specialized laboratory experiments. The mini-symposium will solicit recent studies on computational modeling approaches and high-resolution experimental characterization of the damage processes in complex heterogeneous materials. Special emphases will be placed on multiscale strategies and methodologies that can provide insight into the mechanisms that are responsible for material damage/failure under static or dynamic loading at different length scales. Validated modeling based research approaches and studies including advanced experimental techniques for effective characterization and development of novel structural composites are especially sought.
Possible topics include but are not limited to:
• Multiscale computational approaches across various length scales to better understand the deformation behavior and microstructural failure phenomena such as ductile damage evolution, dynamic plasticity, strain localization, fracture, and shear banding.
• Advanced experimental techniques based on novel small scale methods and measurements of microstructural behaviors.
• Computational methods for bridging length and time scales from micro to macroscale and for effective treatment of local and global instabilities in structural damage/failure analyses.
• Experimental techniques to capture the changing microscale mechanistic interactions linked to material system failure across multiple space and time scales.
• Physics-based macroscale constitutive models linked to microscale mechanistic interactions for multi-scale mechanisms leading to failure and damage analyses.
