Hierarchical honeycomb auxetic metamaterials
(
Nature Publishing Group
, 2015 , Article)
Most conventional materials expand in transverse directions when they are compressed uniaxially resulting in the familiar positive Poisson’s ratio. Here we develop a new class of two dimensional (2D) metamaterials with ...
Honeycomb sandwich panels subjected to combined shock and projectile impact
(
Elsevier Ltd
, 2016 , Article)
Structural response and failure modes of honeycomb sandwich panels subjected to a shock (impulsive pressure) followed by a high velocity projectile impact were investigated using detailed finite element simulations. ...
