Abstract

Ultra-high molecular weight polyethylene (UHMWPE) Dyneema® SK-76 fibers are strong fibers widely used in ballistic protection. On ballistic impact, these fibers undergo multi-axial loading, i.e. fibers are loaded in multiple different deformation modes. It is important to understand the failure of these fibers to improve their ballistic performance. Particularly, it is important to understand the failure strains of UHMWPE fibers under such loading conditions. In this study, we investigate the compliance of the experimental set up used for tensile testing and multi-axial loading of yarns in order to calculate failure strains from experimental data.
