Simulation of an explosion-proof bin made of relaxation material

Abstract

The article discusses the numerical simulation of a blast wave interaction with a relaxation multiphase material used in design of the destructible protection bin with combined method of suppression of the blast damage effects. Numerical simulation of shock-wave systems and processes occurring during the detonation of a condensed high explosive (HE) in semi-open (open at the top) explosion-proof bins was obtained, including when one which uses multiphase gas-liquid material (at a first approximation – water-bubble mechanical foam) as relaxation substance that absorbs the explosion energy and thus reduces the damaging effect of the blast waves.
