Use of the Split Hopkinson Pressure Bar on Performance Evaluation of Polymer Composites for Ballistic Protection Purposes

Abstract

This article presents a review of the split Hopkinson pressure bar uses on evaluation of polymer composites ballistic material’s dynamic mechanical properties A small introduction concerning the equipment is given, followed by a summarization of the most recent published studies relating to dynamic compressive tests used to study dynamic properties of ballistic polymeric composites such as Young's modulus, maximum stress, strain at maximum stress, tenacity and maximum strain, as well as the sensitivity of these properties to changes in the applied strain rate.
