Abstract

Well-controlled hypervelocity impact experiments, conducted in support of the Space Station Shielding Program, were numerically modeled using two sophisticated hydrocodes, the multi- dimensional hydrodynamics code CTH and the Smoothed Particle Hydrodynamics code (SPH). The experiments simulated the impact of space debris on single and double (Whipple shield) plate configurations. Impact velocities on the order of 10 km/s were applied to gram sized flier plates and spherical projectiles that struck thin (less than 1 cm) aluminum and steel plates. Computational predictions of the debris cloud dynamics and plate damage for these experiments were analyzed and correlated with the data obtained from pulsed laser photographs.
