Abstract
In this research, a re-entrant (RH) lattice (called Proposed RH) was designed by tapering the inclined struts of the modified re-entrant structure (Choudhry et al. in Comp Part B: Eng 228:109437 [10]) to achieve enhanced energy absorption properties. In-plane quasi-static compression tests were conducted on 3D printed specimens followed by finite element (FE)-based numerical modeling. Results from FE and experimental analysis were used to investigate the compressive deformation behavior and estimation of energy absorption performance. The analysis results indicate that the proposed RH structure outperforms the conventional RH structure in energy absorption efficiency by 34.41% and in specific energy absorption by 67.25%. The energy-absorbing performance of 3D printed auxetic structures demonstrated here offers insight into the design of lightweight, high-performance structures for defense and protective engineering applications.
