Abstract

Considering the relations between the damage of space vehicle suffered in hypervelocity oblique impact and the configuration of the secondary debris cloud,Smoothed Particle Hydrodynamics(SPH) technique is applied to study the configuration of the debris cloud generated in a hypervelocity oblique impact.Relations between the configurations of the debris cloud and the impact parameters,such as impact velocity,projectile diameter and plate thickness are analyzed.The results show that the expanding velocity and dimension of the secondary debris increase with the increasement of the impact velocity and the projectile diameter,and decrease as the plate thickness is increased.
