摘要
研究了面内冲击载荷作用下不同形状单胞的动态变形机制及能量吸收特性。在相对密度及单胞边长尺寸一致的条件下,讨论了三种不同形状的单胞(三角形、正方形和六边形)的冲击变形模态。在该基础上,分析了一定冲击速度下,几何拓扑结构对单胞能量吸收特性的影响,对于蜂窝材料的微结构设计具有指导意义。
The dynamic deformation and the energy absorption mechanism of cells with different geometrical topology under in-plane impact loading have been studied. Firstly, the deformation mode of cells with three different shapes （triangle, square and hexagon, respectively） is discussed when their relative density and the side lengths are the same. Then, the energy absorption mechanism of the cells with same relative density but different shapes is analyzed under a certain impact velocity. This work will provide the theoretical guidance in the microstructure design of the honeycombs.
