Experimental modelling and numerical simulation of high- and hypervelocity space debris impact to spacecraft shield protection

Results of three sets of experiments modelling space debris impact to spacecraft shield protection in velocities range of 0.5-6.5 km/s are presented. Numerical simulation in the experiments conditions was performed with the help of 3D code KERNEL based on the SPH-method (Smoothed Particles Hydrodynamics) and assigned to obtain prompt solutions of perforation and damage of multilayered and multisheet bumpers under the high- and hypervelocity impact of single particles. Results of numerical simulation are in a good agreement with experimental data.
