本文主要介绍了立方体多孔材料的几何结构。为了研究其作为吸能材料的动力学性能,运用分别基于Mises和Tresca屈服准则的超折叠单元理论(Super Folding Element Theory),分别对实际模型和简化模型的四边形蜂窝材料做动力学理论分析。并通过数值仿真的方式应用有限元方法分析了对比分析立方体多孔材料和四边形蜂窝材料的动力学性能。
This article mainly introduces the geometric structure of cubic porous materials. In order to study its kinetic properties as an energy-absorbing material, the kinetic theory analysis of the quadrilateral honeycomb material of the actual model and the simplified model are respectively carried out by using the Super Folding Element Theory based on the Mises and Tresca yield criteria respectively. The dynamic behavior of cubic cellular material and tetragonal honeycomb material was compared by finite element method through numerical simulation.
