Abstract

Abstract

The anti-blasting and absorbing energy mechanisms of composite protective structure under blasting loads were numerically simulated by applying ANSYS/LS-DYNA. The energy distribution regulation shows that the foam concrete has greater effects of the reflection and absorbing energy, and changes the energy distribution in the protective structure. The more energy is absorbed by top layers，the energy in the bottom layer is only 14% of that in the structure without absorbing energy layer.
