Variation of Poisson’s Ratio with Axial Strain for Three-Dimensional Reentrant Auxetic Structures

Abstract

This study presents numerical investigations of the influence of structural parameters on the variation of the Poisson ratio with axial strain for auxetic structures. Three-dimensional reentrant structures were considered with variable strut thickness to length ratio and reentrance angles. The variation of the volume, relative density, and relative stiffness with axial strain was also studied.
