Auxetic foams counter-intuitively expand (shrink) under stretching (compression). These
foams can exhibit superior mechanical properties such as resistance to shear and …

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 …

The continuous advancement of multifunctional materials is reshaping our way of life and
paving the door for innovative things for us to probe the world and ourselves. Multifunctional …

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 …

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 …

We tested whether conventional and auxetic (negative Poisson's ratio) foam indentation
response fits with classical indentation theory. We first made foam cubes with 20–25 mm …

Sports concussions are a public health concern. Improving helmet performance to reduce
concussion risk is a key part of the research and development community response. Direct …

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 …

In this paper, an innovative concept is proposed, based on the hexachiral auxetic frames
filled with foams with enhanced energy absorption capabilities. Numerical assessments of …

Auxetic behavior is a promising new area for use in defense applications. In comparison to a
conventional material, an auxetic material has superior properties because of having a …
