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

Experimental and numerical investigations were performed on explosive shock wave around the wall and explosive loads on the protective wall.The transducer pressure measurement technology was adopted to measure the pressure distribution around the protective wall.Pressure history on the forward and backside of the protective wall was gained,Based on ALE algorithm and JWL state equation,a numerical simulation was carried out to simulate the above complex phenomenon of mechanics of explosion.Both experimental and numerical results are in good agreement,which show the inherent mechanism of blast wave around the wall and provide a reference for reinforcement mechanism study of the protective wall.
