Abstract:
The use of semi-infinite, bi-element targets in depth of penetration DOP testing initially arose from the need to rank performance of ceramic materials under ballistic impact. Ceramics exhibit complex damage responses. Interpretation of DOP results for ceramicmetal target combinations can be difficult and sometimes misleading. Recent work examined bi-element metalmetal targets to determine additional damage mechanisms present in the earlier DOP ceramicmetal target responses. Significant target interactions were demonstrated in either combination with or in addition to specific damage mechanisms inherent in the ceramic response. The target interactions considered before arose from mismatched densities at the targettarget interface. Through an analytical model, the density effect and time-dependent mechanisms were separated. The current work, which includes titanium diboriderolled homogeneous armor RHA and titanium diboridetitanium alloy bi-element target designs provides target combinations that are density-matched and strength-matched. The current work presents these new data and provides an analysis to normalize DOP responses for all target combinations. A ceramic damage function that could partially link experimental results to analysis is defined.
