Abstract

Abstract

To study the effect of water on charge mass for demolishing steel plate, the relationship of charge mass between steel plate backing on air and backing on water is analyzed. The results show that the charge mass for backing on water is 3.68 times the charge mass for backing on air. The charge mass is calculated with FEM method for explosions with steel plate backing on air and water. The results show that the charge mass for steel plate backing on air is 3.5 times the charge mass for steel plate backing on water, which is accordant with theoretical analysis. So the medium that steel plate backs on is the key factor for determing charge mass of cutting steel plate. The impulses on steel plate are almost equal for backing on air and backing on water, which indicates that the water constraining force on the detonation products can not afeect the charge mass much.
