Weerheijm, J. Sluys, L.J. Publication year 2018 Abstract The deformation-to-fracture evolution of aflexible polymer material under high-strain-rate compressive loadingconducted by a split Hopkinson pressure bar (SHPB) setup was investigated. Representative tests were carriedout at different strain rate levels, followed by the characterization of dynamic damage after each test. Craze andcrack patterns on the end surface of the specimen were carefully analyzed. The failure patterns appear along theradial and circumferential directions. The sequence of their formation with increasing strain/stress level wasrevealed. The mechanisms resulting in the craze and crack patterns were analyzed. The heterogeneous stressdistribution in the specimen and the resultant damage morphologies were demonstrated. This research not onlyshows the deformation-to-fracture evolution of aflexible polymer material under SHPB loading, but also pro-vides a better clarification of the localized stress distribution in the tested material via SHPB technique.
