This paper developed and fabricated four novel hybrid metamaterial structures by combining
honeycomb, re-entrant, and star-shaped unit-cells by additive manufacturing (AM) …

The auxetic lattice structures usually have excellent energy absorption characteristics since
their failed part can resist crushing loads continuously. However, their platform stress is …

Auxetic structures have theoretically superior bending resistance that was previously
inaccessible. Compared with the planar two-dimensional (2D) auxetic structures, the three …

This paper presents an analytical model to investigate the static behaviour of sandwich
plates comprised of two isotropic face sheets and a honeycomb core. Through-thickness …

Aiming at the problems of stress concentration and negative Poisson's ratio in the
deformation process of the re-entrant structure, a cosine-shaped re-entrant structure …

In this study, a novel self-similar re-entrant auxetic metamaterial (SREAM) was designed to
improve its mechanical performance compared with the conventional re-entrant structure …

The present study unravels the deformation mechanisms observed during the static inclined
compression of re-entrant honeycomb (RH) auxetic structure. A pushover Riks analysis is …

Apart from the inherent anomalous behaviour under tensile and compressive structures,
auxetic structures have shown improved energy absorption characteristics that are of prime …

The influence of lattice structural design on the mechanical property has been abundantly
investigated, however, the effect of material on the load-carrying performance and energy …

Re-entrant auxetics offer the potential to address lightweight challenges while exhibiting
superior impact resistance, energy absorption capacity, and a synclastic curvature …
