ABSTRACT
This paper presents results from simulations of shock wave propagation in ceramic rods with and without confinement. The experiments involved steel and graded-density flyer plates impacting sleeved and unsleeved AD995 ceramic rods. The main objectives of simulating these experiments were: 1) to validate the Rajendran-Grove (RG) ceramic model constants, and 2) to investigate the effects of confinement on damage evolution in ceramic rods, as predicted by the RG model. While the experimental measurements do not indicate the details of damage evolution in the ceramic rod, the numerical modeling has provided some valuable insight into the damage initiation and propagation processes in ceramic rods.
