Crushing behavior and optimization of sheet-based 3D periodic cellular structures

Sheet-based 3D periodic cellular structures attract great attentions due to their lightweight and excellent mechanical properties. Unlike other traditional honeycombs and lattice structures, sheet-based cellular structures consist of triply periodic minimal surface (TPMS) cores, which are continuous through space with a porous cavity surrounded by continuous surfaces. In this study, the crashworthiness of four types of TPMS sheet structures...
