An experimental and numerical investigation of fatigue life and crack propagation in two-dimensional perforated aluminum structures is presented. Specifically, the performance of positive Poisson’s ratio (PPR) geometries using circular holes is com

A novel porous mechanical metamaterial with variable Poisson’s ratio (VPR) is proposed for compression and impact applications. Constructed by stacking layers of varying void aspect ratio, VPR structures combine the collapsing penetration resistanc

Two-dimensional tessellations of alternating high-aspect ratio voids, such as ellipses, are known to induce auxetic behavior in engineering materials. An undesirable side effect of using high-aspect ratio shapes is an increased stress concentration a

This study presents an evaluation of the static and dynamic mechanical behavior of low porosity, ductile two-dimensional auxetic metamaterials. The full in-plane displacement fields and the eigenmodes of different geometric structures were investigat

The paper investigates the effect of stitching on the post-impact flexural performance of two classes of thin carbon/epoxy laminates. Unstitched and stitched laminated samples were first impacted with energies ranging between 1 J and 8 J by an instru
