A coupled elastoplastic damage model is proposed for the description of anisotropic concrete under compression-dominated stresses. The model is applied to typical concrete in various loading conditions. Damage evolution law and plastic damage coupling are described by using the framework of irreversible thermodynamics.

AbstractWe propose a formulation for tracking general crack paths in elastodamaging materials without mesh adaptivity and broadening of the damage band. The idea is to treat in a unified way both the damaging process and the development of displacement discontinuities by means of the regularized finite element method. With respect to previous authors’ contributions, a novel damage evolution law and an original crack tracking framework are proposed. We face the issue of mesh objectivity through several two-dimensional tests, obtaining smooth crack paths and reliable structural results.
