- Summary
- Two-dimensional axisymmetric calculations were performed with the Eulerian hydrocode MESA2D and the Lagrangian structural analysis code PRONTO2D. The calculated stress distributions were compared shortly after impact and found to be similar in magnitude and profile. For certain geometric configurations, the interaction of the kinetic energy penetrators with the ceramic targets produce high compressive principal stresses as well as, significant tensile principal stresses ahead of the projectile/ceramic interface. The principal tensile stresses fracture the ceramic ahead of the penetrator. The crack trajectories measured from a recovered ceramic target were compared with crack trajectory estimates based upon MESA2D principal stress states within the tile. The fracture process degrades the ceramic and allows the projectile to penetrate a fractured ceramic media. 12 refs., 3 figs.
