Safety glass is an important tool in protecting people in event of an attack or accident. Therefore predicting it's accurate response is the key to study blast mitigation and crash events. Glass is brittle and cannot withstand large strains, thus the polymeric interlayer acts as a membrane providing additional energy absorption. Here we develop constitutive models for rubber and glass, the two main constituents of safety glass, which can also be used independently for other applications not limited to the architectural and automotive industry. We present a phenomenological model for rubber which can not only predict the primary hyperelastic and viscoelastic behavior at low to high strain rates, but also takes into account hysteresis and Mullins effect. The model for rubber is consistent with the laws of continuum mechanics and can successfully predict the response of a wide range of polymers using a limited set of experimental data. The model for glass is inspired from ceramic like brittle materials. Finally, we study the impact simulation of safety glass using the standard material models from the LS-DYNA library, specifically made up of polyvinyl butrayl and float glass.
