Abstract

Cellular materials are used as impact energy absorbers due to their large densification strain at the plateau stress during the plastic compression. For a cellular rod struck by a rigid object, the critical impact velocity is determined. If the impact velocity is higher than the critical impact velocity, the elastic wave will be
followed by plastic shock waves. Plastic shock waves and shock arrest are investigated analytically for longitudinal impacts. Shock behaviors are characterized for material design purpose and will be used for impact protection.
