Study on quasi-static mechanical properties of four 3D-printed bio-inspired structures based on functional relationship

Numerous complex structures with excellent mechanical properties have been created to adapt to impact conditions and these bio-inspired structures play a significant role in applications of protective engineering in the future. In this paper, the three-dimensional finite element models of the normal honeycomb structure, the concave honeycomb structure, the inclined column honeycomb structure and the imitational peanut shell structure are...
