Auxetic Textiles

Acta Chimica Slovenica, 2014
Common materials have Poisson’s ratio values ranging from 0.0 to 0.5. Auxetic materials exhibit negative Poisson’s ratio. They expand laterally when stretched longitudinally and contract laterally when compressed.

Strain‐Activated Mechanical Metamaterial With Programmable Dual‐Phase Stiffness and Enhanced Energy Absorption

Advanced Materials Technologies, EarlyView.
A strain‐activated mechanical metamaterial is developed to achieve programmable dual‐phase stiffness through an intrinsic geometric locking mechanism. Finite element modeling and parametric analysis identify the key design parameters governing activation strain, stiffness transition, and energy absorption.
