3D simulation of concrete cracking: probabilistic formulation in a parallel environment

This work presents a probabilistic crack approach based on the Monte Carlo method, implemented in a 3D fully parallelized finite element code (Paz, [1]). The cracking scheme used is the discrete crack approach. In this approach the heterogeneity of the material is taken into account by considering the properties to vary spatially following a normal distribution determined by the mean and the standard deviation of the considered material properties.Fracturing is modeled by 3D interface elements generated in a previously defined region within the mesh (Paz [1]). The interface elements are triangular base prisms connecting adjacent faces of neighboring tetrahedra. These elements simulate crack opening through relative displacements between the triangular faces.
