Following high profile, life changing long term mental illnesses and fatalities in sports such
as skiing, cricket and American football—sports injuries feature regularly in national and …

Auxetic materials exhibiting a negative Poisson's ratio are shown to have better indentation
resistance, impact shielding capability, and enhanced toughness. Here, we report a class of …

This book discusses bulk solids that derive their mechanical properties not from those of
their base materials, but from their designed microstructures. Focusing on the negative …

In this work, an analytical model of a 3D re-entrant auxetic cellular structure has been
established based on energy method. In the model the overlapping of the struts as well as …

In recent years, 3D structures with negative Poisson's ratio (auxetic) have attracted great
interest. Many polymer and metal 3D auxetic structures have been manufactured using …

Auxetic lattice structures are prospective candidates in many engineering applications
because of their unique negative Poisson's ratio effect as well as excellent mechanical …

Auxetic mechanical metamaterials are artificially architected materials that possess negative
Poisson's ratio, demonstrating transversal contracting deformation under external vertical …

In this study, 2D triangular anti-trichiral structures and auxetic stents, under compression,
were introduced. The cores of the anti-trichiral structures were the equilateral triangles. The …

We describe here the quasi-static crushing behavior of novel classes of multiphase (hybrid)
hierarchical lattice metamaterials. The first class is represented by a hybrid architecture …

Abstract Three-dimensional (3D) fabrics with negative Poisson's ratio (NPR) are known as
3D auxetic fabrics. They expand (or contract) in the direction perpendicular to stretch (or …
