摘要

提出了一种新的屈曲诱导耗能机械材料的设计思路。提出了一种拓扑优化公式，其中超材料的单元格的力-位移曲线被定制为在质量约束下最大限度地减少屈曲引起的耗散能量。提出了一种两阶段算法，从一致的初始猜测中找到最优结果。基于设计者直觉的优化设计比结构原型具有更大的屈曲耗散能。

Topology Optimization of Metamaterials for Energy Dissipation

A novel design concept for buckling-induced mechanical metamaterials for energy dissipation is presented. A topology optimization formulation is proposed, where the force-displacement curves of the unit cells of the metamaterials are tailored to maximize the buckling-induced dissipated energy in a mass constraint. A two-phase algorithm is proposed to find the optimized result from a uniform initial guess. The optimized design has a larger amount of buckling-induced dissipated energy than the structural prototypes based on the designers' intuition.
