Auxetic Films with a Miniaturized Cellular Structure

, 2018
Auxetic materials represent a relatively new class of materials that are characterized by a cellular structure and a negative Poisson coefficient. Auxetics are extremely useful for morphing applications thanks to their synclastic deformation capability ...

Auxetic structure optimization for double-walled hull crashworthiness using response surface methodology

Results in Engineering
One type of negative Poisson's ratio (NPR) structure, called auxetic, has been widely studied due to their superior mechanical properties, including enhanced energy absorption capabilities. However, their application in marine structures, particularly in

New auxetic materials

, 2000
Materials with negative Poisson's ratios (auxetic) exhibit the very unusual property of becoming wider when stretched and narrower when squashed. This thesis presents a global classification system for auxetics based on the geometry and deformation ...

Shear Properties of the Re-Entrant Auxetic Structure Made via Electron Beam Melting [PDF]

, 2015
While the tensile/compressive mechanical properties of the re-entrant auxetic cellular structure have been relatively well modeled, their shear properties including the shear modulus and shear strength have not been investigated.
