摘要: The book analyzes quasi-static fracture in plain concrete and reinforced by means of constitutive models formulated within continuum mechanics. A continuous discontinuous modelling approach was used. Using a approach, analyses were performed using finite element method four different models: enhanced isotropic elasto-plastic, damage, anisotropic smeared crack coupled elasto-plastic-damage model. equipped with characteristic length micro-structure non-local second-gradient theory, so they could describe the formation localized zones certain thickness spacing related deterministic size effect. FE results converged to via mesh refinement. In addition, numerical cracks including cohesive (interface) elements XFEM presented which also properly regularized. Numerical compared corresponding laboratory tests from scientific literature own tests.
