Abstract

In the paper SPH (Smoothed Particle Hydrodynamics) methods in AUTODYN-2D is used to investigate the characteristics of debris clouds propagation inside the gas-filled pressure vessels for hypervelocity impact on the pressure vessels. And a better correlation between experimental and numerical results is obtained. The result shows that the venting time of vessels is related with "vacuum pole" which in impact-axial direction, which gas pressure can reduce the damage of the debris clouds\´ impact on the rear wall vessels when the pressure value is in a certain range.
