(In)efficacy of architected auxetic materials for impact mitigation: Investigations of energy absorption and force distribution
conference paper
Auxetic (negative Poisson's ratio) materials have been shown to provide improved indentation resistance, shear resistance, fracture toughness, and energy absorption [1]. As such, they are promising options for impact mitigation in military or space contexts. Auxetic materials are rare in nature, and must therefore be designed and manufactured artificially in order to be used practically. This design process is well understood in the linear and static regime, but little attention has been paid to the local behavior of such architected materials undergoing finite deformation at high rates and the subsequent effects of design choices for impact mitigation in practical protection scenarios.
