Originální abstrakt

A numerical parametric study has been performed on a Brazilian disc test with a central notch. In this study, the post peak crack initiation and propagation in this test is presented based on a concrete damaged plasticity model. The influence of the fracture energy Gf and the shape of the post peak tensile softening curve on the crack initiation were considered. Focus was placed on the notch tip displacements as to separate mode I and mode II displacements. For this, the nodal displacements were transformed based on the geometry (notch inclination angle), linear elastic fracture mechanical criteria, and plasticity conditions in order to help to distinguish the fracture modes. It was observed that, by choosing the right transformation angle, mode I and mode II fracture processes can be distinguished on such a test.
