Modeling of structures subjected to impact: concrete behaviour under high strain rate

This paper deals with a viscoplastic model which is the natural way to take into account the rate effect. Consideration of viscosity averts the habitual mesh sensitivity when strain softening is introduced by preserving the well-posedness of the initial boundary value problem. Modeling can constitut...
