Re-Entrant Honeycomb Auxetic Structure with Enhanced Directional Properties

Materials, 2022
This paper presents a modified re-entrant honeycomb auxetic structure. The structure is constructed by adding an additional horizontal member between the vertical and re-entrant member of the semi-re-entrant honeycomb model to increase the overall ...

Dynamic Performance of a 3D Re-entrant Structure

Mechanics of Materials, 2020
In this study, the mechanical performance of a three-dimensional (3D) re-entrant structure subjected to dynamic compression was experimentally investigated using a high-speed Instron machine. Quasi-static tests were conducted for comparison.

An investigation of in-plane tensile properties of re-entrant chiral auxetic structure

International Journal of Advanced Manufacturing Technology, 2018
A new auxetic structure, re-entrant chiral auxetic (RCA) structure, is proposed for the first time in this paper. The RCA structure combines the topological features of hexagonal re-entrant and anti-tetrachiral honeycombs.
