Testing the Explosion Resistance and Energy Absorption of
Concrete structures can suffer damage from the shock waves caused by explosions. However the damage can be mitigated in practice by increasing the size of the energy-absorbing interlayers to improve the antiknock performance of the concrete. The aim of this paper is to investigate the energy-absorbing capability of a composite structure of polyurethane-foamed aluminum and concrete.
