The paper presents a numerical model for reinforced concrete and its application in the simulation of concrete fracture under static and dynamic loading. In particular, a regularized formulation of damage-plasticity theory is employed in order to preserve the well-posedness of the mathematical model in the simultaneous presence of damage and softening. The model is implemented in the FEAP finite element package. The simulations are limited to two-dimensional configurations of a beam in four-point bending, which was examined experimentally by Eibl et al. Mesh and model parameter dependence studies are performed.
