Crashworthiness optimization of bio-inspired hierarchical honeycomb under axial loading

Bio-inspired engineering designs have gained great attention due to their excellent structural and mechanical properties. To study the hierarchical structural characteristics of natural structures, a finite element (FE) model of novel bio-inspired triangular hierarchical honeycomb was presented to investigate its axial energy absorption characteristic using the nonlinear finite element software LS-DYNA. It was found that the specific energy...
