Mineral-filled polymers are the candidate materials to manufacture structural safety components of motor vehicles due to the remarkable combination of price, density, and toughness. The initiation of void formation enhances their energy absorption capabilities to minimise the destructive consequence of unavoidable collisions. Although several constitutive models have been implemented in finite element solvers, very few are currently used by CAE engineers to design the next generation of sustainable cars due to their extensive experimental and numerical costs. The seminar will present a new elastic-viscoplastic constitutive model that efficiently simulates the mechanical behaviour of mineral-filled polymers when subjected to multi-axial stress states at different strain-rates.
