Modeling the Rebound of Ballistic Roma Plastilina No. 1 Clay

Abstract

Accurate modeling of ballistic Roma Plastilina No.1 (RP 1) clay is very critical to understanding the load transfer between the armor and the clay. Our previous developed model for the RP 1 clay did not account for the rebound due to the limited test data used for the model development. In this study, additional dynamic impact experiments were conducted to provide test data to characterize the rebound. The experiments showed that the rebound depended on the impact velocity and could be as high as 15. The material model for the RP 1 clay was recalibrated to account for the rebound.
