Summary

This special issue focuses on the optimization design and simulation of advanced polymer/metal matrix composites at various length scales, ranging from nano/molecular to full product/structure level. The research targets mechanical issues and performance of advanced composites and structures, with emphasis on the application and development of novel numerical methods and simulation tools, such as molecule dynamics, phase field method, peridynamics, reduced-order-homogenization method and advanced finite element methods, etc. The key areas of interest include all aspects related to design, validation, characterization and testing of composite materials, including but not limited to nanocomposites, structural and functional composites, novel composite material concepts, and also green and bio-based composites.

    Investigation of Projectile Impact Behaviors of Graphene Aerogel Using Molecular Dynamics Simulations

    Xinyu Zhang, Wenjie Xia, Yang Wang, Liang Wang, Xiaofeng Liu
    CMES-Computer Modeling in Engineering & Sciences, DOI:10.32604/cmes.2023.046922

    Abstract Graphene aerogel (GA), as a novel solid material, has shown great potential in engineering applications due to its unique mechanical properties. In this study, the mechanical performance of GA under high-velocity projectile impacts is thoroughly investigated using full-atomic molecular dynamics (MD) simulations. The study results show that the porous structure and density are key factors determining the mechanical response of GA under impact loading. Specifically, the impact-induced penetration of the projectile leads to the collapse of the pore structure, causing stretching and subsequent rupture of covalent bonds in graphene sheets. Moreover, the effects of temperature on the mechanical performance of… More >

    Particle Discontinuous Deformation Analysis of Static and Dynamic Crack Propagation in Brittle Material

    Zediao Chen, Feng Liu
    CMES-Computer Modeling in Engineering & Sciences, Vol.139, No.2, pp. 2215-2236, 2024, DOI:10.32604/cmes.2023.046618

    Abstract Crack propagation in brittle material is not only crucial for structural safety evaluation, but also has a wide-ranging impact on material design, damage assessment, resource extraction, and scientific research. A thorough investigation into the behavior of crack propagation contributes to a better understanding and control of the properties of brittle materials, thereby enhancing the reliability and safety of both materials and structures. As an implicit discrete element method, the Discontinuous Deformation Analysis (DDA) has gained significant attention for its developments and applications in recent years. Among these developments, the particle DDA equipped with the bonded particle model is a powerful… More >
