| Abstract: | The explosion process of a steel ball impacting explosive cylinder with two protecting gapped-plates was simulated by using LS-DYNA3D.In this paper,coupled solid-fluid analysis and dynamic contact mode were employed.The critical speed of the ball,was obtained at which the explosive was initiated.The peak pressure of products after explosive detonation was calculated. |
