N2 - The modelling of ultra-high molecular weight polyethylene (UHMWPE) fibre composites under impact loads has been the subject of numerous studies and has been attempted via different approaches. In this work, a finite element model is developed to predict the energy absorption at the interfaces of these laminates, under varying rates of impact. Cohesive elements are employed to model the behaviour of interface regions between sub-laminates at low strain rates. The model is then extended to ballistic impact rates, to capture the energy absorption mechanisms of the material and thereby facilitate better understanding of its mode I and mode II deformations. Subsequently, parametric studies are performed to determine the effect of physical parameters such as in-plane and through-thickness dimensions of the target on the dissipation of energy at the interfaces.
