TL;DR: In this paper, the effect of cell-wall thickness on the deformation mode of metallic auxetic reentrant honeycomb was firstly studied, and also the negative Poisson's ratio (NPR) effect on the crushing stress was also clarified by the quasi-static compressive experiments.

TL;DR: In this paper, the quasi-static compression behavior of graded metallic auxetic reentrant honeycomb was firstly studied using the selective laser melting method, and the unidirectionally-graded auxetic honeycomb (UGAH) with the equal mass were fabricated to conduct the compression tests.

TL;DR: In this article, the structure response of end-clamped sandwich beam with auxetic reentrant hexagonal aluminum honeycomb core locally subjected to foam projectile with high-velocity impact was experimentally and numerically studied.

TL;DR: In this paper, the effect of shape parameter on the deformation mechanisms of the modified rhombic dodecahedron (RD) lattice structure was discussed, where three different deformation modes were observed.

TL;DR: In this paper, the role of a single geometric defect on the mechanical responses and energy absorption of the lattice structures with stochastic geometric defects originated from additive-manufacturing was examined, where X-ray computed tomography (CT) was employed to capture the morphology and distribution of process-induced defects.
