摘要：

Triply periodic minimal surface (TPMS) has many excellent properties, such as stable energy absorption, a high specific strength, a large surface area, etc. The functional multi-stage design and research of TPMS lattices were carried out to improve the mechanical performance. The deformation modes and curves of three uniform TPMS lattices (Primitive, Gyroid, and Diamond) and their hybrid lattices were analyzed by quasi-static compression experiments and numerical simulations. Based on the uniform TPMS lattice, hybrid sheet TPMS lattices were designed to realize the multi-stage energy absorptio...
