Title: A computational study of projectile shape dependence on phase change phenomena with comparisons to experimental data

Abstract

To make an estimate of the current state of predictive capabilities of hydrocodes for impacts where phase changes may be important, we have simulated a series of experiments where a zinc sphere, rod, and plate impact thin zinc plates at 5 km/s. The experimental data consists of radiographs of the debris cloud and visual evidence of the damage in an aluminum witness plate. CTH was used to simulate the three experiments noted above. A detailed comparison of the simulated debris structure and subsequent damage will be made with the available data. In general, the CTH predictions match the experimental record.
