Abstract
The material behavior under dynamic processes, such as ballistic impacts, demands a deep knowledge of high-rate testing techniques, dynamic material response and dynamic material models. In this field, ultra-high molecular weight polyethylene (UHMW-PE) composites have been proven to be extremely effective against such threats. During a ballistic impact, a transverse shock wave travels through the material layers. When the shock wave is reflected at the rear face of the component, tensile stresses are created through the material thickness. This dynamic sequence produces a damage mechanism which combines shearing within the top plies of the material, and bulging and delamination at the rear face of the component.
