Finite element analysis of diagonal tension failure in a reinforced concrete beam is performed by using different meshes and different concrete crack models. It is found that inserting specific finite element bands in the mesh to model diagonal cracking improves crack localization and propagation. Multi-directional fixed crack and rotating crack models exhibit convergence problems, and lead to flexural or shear compression failure rather than diagonal tension failure. It is shown that the Multi Equivalent Series Phase Model clearly describes the complex mixed mode fracture that is typical of diagonal tension failure.
