Abstract : This work documents two separate studies: one that evaluates the effect material interfaces have on the ballistic response of ceramics; and one that evaluates numerical approaches to model the composite Dyneema. The first study uses several configurations where a ceramic is attached to a metal backing plate and the effect of bonding the plate to the substrate is evaluated. Two material models are used in this study, the Tonge-Ramesh (TR) ceramic model and the Johnson-Holmquist-Beissel (JHB) ceramic model. In the second study several approaches are used to evaluate the ability to model the ballistic response of Dyneema. Experimental ballistic data were provided by the Army Research Laboratory (ARL) and are used to evaluate the numerical approaches. All the work presented herein use a prerelease of the 2017 Beta version of the EPIC code. The remainder of this report presents the results for the bonding study followed by a discussion on modeling Dyneema.
