| Abstract: | Using LS-DYNA software,ALE algorithm and the multi-material fluid-solid coupling manner,blast shock waves propagation in the ammunition caves of round and arc section are studied by numerical simulation.The results show that shock wave pressures at the corresponding point of explosive axis caves of round section and arc section are almost equal. |
