Abstract In most previously constructed lattice inspired structures, atoms were not included. Thus, their mechanical behaviours might not well simulate the lattice structures. In the present work, a body-centred cubic (BCC) inspired structure with atoms as reinforced nodes and atomic bonds as connected struts, was additively manufactured using Ti-6Al-4V alloy via a selective laser melting. Results of mechanical compression test and finite element analysis revealed the higher yield strength, collapse strength and energy absorption capability of the BCC-inspired structure with reinforced nodes than the ones without reinforcement.

激光选区熔化法制备节点增强体心立方晶格结构的力学性能

摘要 在大多数先前构建的晶格启发结构中，不包括原子。因此，它们的机械行为可能不能很好地模拟晶格结构。在目前的工作中，使用 Ti-6Al-4V 合金通过选择性激光熔化增材制造了一种受体心立方 (BCC) 启发的结构，其中原子作为增强节点，原子键作为连接支柱。力学压缩试验和有限元分析的结果表明，受 BCC 启发的结构具有更高的屈服强度、倒塌强度和能量吸收能力，有加固节点比没有加固的结构更高。
