Description
Summary:This article investigates the energy absorption performance and deformation mechanism of 316L stainless steel (SS316L) triply periodic minimal surface (TPMS) cellular structures fabricated by a selective laser melting (SLM) technique. The as‐built specimens are subjected to abrasive blasting treatment to improve the surface quality of the printed parts, in order to reveal the true surface and mechanical characteristics of the TPMS structures. It is found that the P‐type structure outperforms the G‐type structure with a higher energy absorption capability at low relative densities (
