RESEARCH INTO IMPACT EFFECT ON WALL AND FLOW AROUND WALL OF EXPLOSIVE SHOCK WAVE

Experimental and numerical investigations were performedon explosive shock wave around the wall and explosive loads on theprotective wall. The transducer pressure measurement technology was adoptedto measure the pressure distribution around the protective wall. Pressurehistory on the forward and backside of the protective wall was gained, Basedon ALE algorithm and JWL state equation, a numerical simulation was carriedout to simulate the above complex phenomenon of mechanics of explosion. Bothexperimental and numerical results are in good agreement, which show theinherent mechanism of blast wave around the wall and provide a reference forreinforcement mechanism study of the protective wall.
