Abstract : The use of semi-infinite, bielement targets arises from the previous development of the depth of penetration (DOP) testing for ranking ceramic materials. Performance is measured by the DOP of a long rod penetrator into a semi-infinite steel backplate after passing through a ceramic applique. Here, an additional step was taken before evaluating a ceramic applique. Metallic bi-element targets were tested to identify possible nonmaterial-related effects present in DOP testing. As a result, this work identifies and postulates a dynamic effect inherent in both metal/metal and ceramic/metal bielement targets, establishing a clear separation between kinematic effects and ceramic responses.
