Modelling the dynamic response of concrete with the damage plasticity model CDPM2

Abstract

. Combinations of damage mechanics and the theory of plasticity have shown to be suitable for modelling concrete’s quasi-brittle response in tension and low-confined compression, as well as the ductile response in confined compression. In this work, the recently proposed damage-plasticity constitutive model CDPM2 has been extended to the modelling of plain and reinforced concrete subjected to dynamic loading by making the damage part dependent on the strain rate. The approach is then applied to a dynamic compact tension test and a slab subjected to air blast loading for both of which experimental results have been reported in the literature.
