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 …

Advanced sandwich structures have emerged as new multifunctional structures with low
density and good mechanical performance. Sandwich composites have high strength to …

Featured Application Auxetic open cell foam was used as the comfort layer within a sports
helmet and has been shown to reduce the severity of linear impacts. The work undertaken …

Poisson's ratio is an important property defining the relationship between lateral and
longitudinal deformations. While most conventional materials have positive Poisson's ratios …

Auxetic Textiles provides a detailed introduction to the basic properties of auxetic materials
and how they differ from conventional materials, particularly auxetic textiles, such as …

In this study, the ballistic impact behavior of auxetic sandwich composite human body armor
was analyzed using finite element analysis. The auxetic core of the armor was composed of …

Auxetic materials behave unconventionally under deformation, which enhances material
properties such as resistance to indentation and energy absorption. Auxetics, therefore …

The weak stiffness and strength of materials with negative Poisson's ratio limits their
application. In this paper, three types of novel lattices with negative Poisson's ratio are …

We present here a simplified procedure to manufacture auxetic PU foam via a single
direction thermoforming compression process applied to conventional (pristine) open cell …

This work describes large strain quasi-static and impact tests of a new class of low-cost,
uniaxially thermoformed, transverse isotropic auxetic foams with compression ratio ranging …
