For the space-debris protection problem, it is very important to understand the multi-phase transformation phenomena including elastic and plastic deformation caused by hyper-velocity impact. In this paper, the numerical simulation code, CRATE-2D, was developed to reproduce the hyper-velocity impact phenomena, employing the SPH (Smoothed Particle Hydrodynamics) Method. First, simulation on the impact between a polyethylene projectile and an aluminum target at the impact velocity of 5km/s was performed. Aluminum was assumed to behave as fluid under the high pressure and high temperature condition created by such a high-speed collision. The calculated crater geometry shows a good agreement with the one created by a light-gas gun in our experiment. Second, the impact between a polyethylene projectile and a duralumin bumper at 2.16km/s was simulated. Johnson-Cook model and a simple instantaneous failure model were employed for taking account of material strength and failure criteria. As a result, the kinetic energy distribution of the secondary debris, which reveals the energy transformation mechanism on the hyper-velocity impact, was obtained.
