Materials that become thicker when stretched and thinner when compressed are the subject
of this review. The theory behind the counterintuitive behavior of these so‐called auxetic …

Most materials demonstrate an expansion upon heating, however a few are known to
contract, ie exhibit a negative coefficient of thermal expansivity (NTE). This naturally occurring …

… As for heating time, Chan and Evans [39] proposed that foam samples could not be “set” …
k is a parameter used to assess the deformation resistance offered by an elastic body:(5) k = F …

A theoretical model has been developed for predicting the elastic constants of honeycombs
based on the deformation of the honeycomb cells by flexure, stretching and hinging. This is …

Selective Laser Melting (SLM) is an increasingly employed additive manufacturing process
for the production of medical, aerospace, and automotive parts. Despite progresses in …

Auxetic materials exhibit the very unusual properties of becoming wider when stretched and
narrower when squashed [1], that is they have negative Poisson’s ratios. Apart from the pure …

… Flow does this affect K and G? If I! approaches … This represcnts one example where ;I large
negative II would produce a benefit, by increasing G at the expense of K. Changing the value …

Recent progress in understanding the diversity of midbrain dopamine neurons has
highlighted the importance—and the challenges—of defining mammalian neuronal cell types. …

A microporous, anisotropic form of expanded polytetrafluoroethylene has been found to have
a large negative major Poisson's ratio. The value of Poisson's ratio varies with tensile strain …

Finite element models are developed for the in-plane linear elastic constants of a family of
honeycombs comprising arrays of cylinders connected by ligaments. Honeycombs having …
