Abstract:

Half-symmetric model is used in AutoDyn to simulate Depth of Penetration DoP experiments on aluminum targets with ceramic facing with and without a gap between tiles. Impacts from a .30cal AP M2 projectile are modeled using SPH elements. Model validation runs were conducted based on the DoP experiments described in reference - ARL-TR-2219, 2000. Boundary conditions were modified in order to achieve better data agreement. Further analysis will be conducted to determine the effect of material properties and gap size on DoP. Nicole Cicchetti has joined the project as a graduate student. Will be studying the effect of gaps on DoP of projectiles on ceramic targets. In past reports simulations were on single tiles with no gaps. Will be analyzing DoP to determine what tile geometry will improve the penetration resistance at the gap between two tiles.
