摘要

Investigates the distribution characteristics of secondary debris clouds generated during a hypervelocity oblique impact. A SPH technique coupled with Lagrangian method is applied to calculate the dimension of penetrated hole on the target plate impacted by hypervelocity projectiles at various impact angles. Based on this the influence of the impact angle on the debris cloud distribution is simulated. Compared the results to the experimental data, the calculated results show that the dimension of penetrated hole and the distribution of secondary debris cloud are both well simulated using the coupling method. As the impact angle is increased over 60°, the trajectory of the mass center of normal debris cloud deviates obviously from that of in-line debris cloud, and the particle number of the projectile material contained in the ricochet debris increases markedly.
