Abstract

Triply periodic minimal surface structures (TPMSs) can be used as a substitute for polymeric foams in applications where is necessary to absorb a large amount of energy with high structural deformation. Diamond TPMS offers higher energy absorption per unit weight. This structure is based on the Ashby-Gibson material model that establishes the main mechanical material properties as functions of the relative density and material properties. However, since TPMSs are used in dynamic applications, it is essential to analyse them under dynamic loads. In this study, we investigate the influence of the strain rate on the Ashby-Gibson parameters of sheet diamond Keywords: Triple periodic minimal surface; strain rate; additive manufacturing; diamond; Ashby-Gibson

应变速率对片状金刚石晶格结构ashby-gibson参数的影响

在需要以高结构变形吸收大量能量的应用中，三周期最小表面结构（TPMS）可以用作聚合物泡沫的替代品。Diamond胎压监测系统提供更高的单位重量能量吸收。该结构基于Ashby Gibson材料模型，该模型将主要的机械材料特性建立为相对密度和材料特性的函数。然而，由于TPMS用于动态应用，因此必须在动态负载下对其进行分析。在本研究中，我们研究了应变速率对片状金刚石Ashby-Gibson参数的影响关键词：三周期最小表面；应变率；增材制造；金刚石阿什比·吉布森
