Abstract:

Well-controlled hypervelocity impact experiments, conducted in support of the Space Station Shielding program, were numerically modeled using two sophisticated hydrocodes, the multidimensional hydrodynamics code CTH and the Smoothed Particle Hydrodynamics code SPH. The experiments simulated the impact of space debris on single shields and single Whipple bumper shield plate configurations. Impact velocities on the order of 10 kms were applied to gram- sized flier lates and spherical projectiles that struck thin 1 cm aluminum, titanium, 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 and high-speed X-ray photography. Computational results of both hydrocodes were compared to each other. Whipple bumper shields, Numerical simulation of experiment, Hypervelocity impact, Smoothed particle hydrocode, CTH Hydrocode.
