Modeling and Simulation of Ceramic Arrays to Improve Ballaistic Performance

Abstract

Half-symmetric model is used in AutoDyn to simulate Depth of Penetration (DoP) experiments on SiC tile with and without a gap supported by solid aluminum. Impacts of a .30cal AP M2 projectile over an impact velocity range 700 m/s to 1000 m/s are modeled using SPH elements. Model validation runs with One Tile SiC tiles are conducted based on the DoP experiments described in reference - ARL-TR-2219, 2000. Tile gap is found to increase the DoP as compared to One Tile tiles. The next step will be run simulations on narrower and wider gap sizes and different geometries of tile configurations. Determinations need to be made on what the manufacturers tolerances on tile gaps are and possible filling materials for gaps. DOP is the main measurement to determine which geometry and configuration yield the best results.
