Cardboard honeycomb energy dissipating material (EDM) is used extensively for protection of cargo that is air dropped. Whilst air dropped containers are deployed with parachutes, a significant amount of energy still requires dissipating on impact with the ground. The specification of cardboard EDM in dynamic applications has tended to be ad-hoc with no thorough understanding of the energy absorbing characteristics of the material. This paper seeks to address this gap in knowledge.
