Abstract: Ultrahigh molecular weight polyethylene (UHMWPE) hard ballistic soft laminate (HBSL) is lighter than water and is a protection material for personal and vehicular applications. Based on the well know 1D fiber theory and 2D membrane theory, a multiscale finite element (FE) model of Dyneema® HB26 HBSL is developed in understanding the fundamental physics of in-plane and transverse wave propagation, debonding between laminas in a laminate using mixed mode traction separation law, transverse splitting between fibers in a lamina using the rate dependent non-linear elastic-plastic deformation of polyurethane matrix material, and longitudinal tensile fracture of dyneema fibers using traction laws for transverse splitting of fibrils and stochastic tensile fracture of fibrils. Modeling methodologies of such a multi-scale modeling approach will be developed in different length-scales where the output from a lower length scale model will be incorporated to its upper length-scale models.
