摘要
三周期极小表面金属多孔结构是一种用于轻量化和多功能结构应用的新结构.设计并制备Diamond、Gyroid和Primi-tive 3种TPMS多孔结构,采用选择性激光熔化(SLM)制备3种Ti6Al4V多孔结构样件,研究不同结构的变形行为和能量吸收特性.综合分析表明,不同类型TPMS结构在压缩过程中呈现不同的变形行为和力学响应,该种结构可以用于抗冲击车辆或植入体的应用.
Abstract
Three-periodic minimal surface(TPMS)metal porous structure is a new lightweight structure with wide applications in multifunctional structures.In order to study the deformation behavior and energy absorption of different structures,three TPMS samples with Diamond,Gyroid,and Primitive structures were prepared using the selective laser melting technique.Comprehensive analyses showed that different types of TPMS structures have different deformation behaviors and mechanical responses during compression.The results of this article can be used to design impact-resistant parts in vehicles or implants.
