Crack growth, singularities and wave propagation in auxetic composite materials
An auxetic material is a material which has a negative Poisson's ratio, so they exhibit lateral expansion upon longitudinal tensile loading, or undergo lateral contraction under longitudinal compression. Such materials can exist in cellular form, or along specific axes in certain crystals. The …

CHARACTERIZATION AND MODELLING OF MAGNETO-AUXETICITY, THE MAGNETICALLY INDUCED AUXETIC BEHAVIOR, IN GALFENOL
… alloy (Galfenol) is a magnetostrictive smart material (λsat ~400 ppm) with potential for robust transduction owing to good magneto-mechanical coupling and useful mechanical properties. In addition, Galfenol exhibits a highly negative Poisson’s ratio (denoted by ν) along the <110> …

Modeling and simulation of stochastic phenomena in carbon nanotube-based single molecule sensors
… nanoscale structures could lead to new materials with interesting mechanical properties. One example of such a structure is an interlocking sheet of graphene rings, analogous to macroscopic chainmail. Such a sheet would have interesting properties, as entropic out-of-plane fluctuations …

Additively manufactured aluminium auxetic architecture with targeted mechanical and energy absorption characteristics
Auxetic materials offer unconventional properties owing to their negative Poisson’s ratio (−𝜐) leading to deformation modes and mechanical characteristics different to traditional porous architecture. This leads to favourable outcomes for lightweight applications where precise control of the …

Bistable Auxetic System -- Programming synclastic curvature into 2D Patterning
… inspiration from the transformation process of auxetic materials and embeds this within a bi-stable mechanism. Starting from fundamental geometric research of linear hinges and out-of-plane rotation, geometrical constraints are identified thoroughly for the length-preserving transformation …
