Abstract
A test program recently completed at the Defence Research Establishment Valcartier (DREV) to study the performance of various ceramics using the Depth of Penetration (DOP) method generated a significant scatter in the results. The test results were presented, analysed and discussed in another publication (DREV R-9522). It was not possible to explain the differences in the results obtained for firings performed under very similar conditions by the impact conditions (total yaw angle or impact velocity), no by differences in the target composition or assembly. Using hydrocode simulations where the ceramic was modelled using the Johnson/Holmquist constitutive model, the scatter in the experimental results was investigated and the analysis is discussed.
