Failure simulation and design optimization of bioinspired heterogeneous interfaces by Floquet-based bar-spring model

Interface plays a critical role in the mechanical performance of composites. Lack of a suitable interface design has long been a bottleneck impeding the full exploitation of the mechanical strengths of many superior reinforcement phases such as the high-performance carbon fibers and carbon nanotubes. Here a Floquet-based bar-spring model is developed to simulate the elastic and failure behaviors of three topological designs of heterogeneous...
