COMPARISON OF CRACK PATHS BY USING SELECTED CRITERIA IN BRAZILIAN DISC SPECIMEN
Original language description
A numerical parametric study of the crack propagation under various level of mixed-mode conditions is evaluated. By focusing of the Linear Elastic Fracture Mechanics (LEFM), the model of concrete Brazilian Disc Test (BDCN) with a central notch is considered and its analysis with defined radius R, force P and material properties is performed. The results are obtained by varying the length a of the central notch and its angle of inclination α with respect to the horizontal axis. The crack growth direction is estimated through three different criteria: the maximum tangential stress (MTS) criterion, the strain energy density (SED) criterion and the crack tip displacement (CTD) criterion. This study involves the classical single-parameter fracture mechanics concept, in which the stress distribution in a cracked specimen is described by the stress intensity factors (SIFs). The Williams solution of the crack-tip stress and displacement fields is taken into account. As a comparison, the solution is also provided with J-Integral. The model is created with the finite element method software ANSYS. Lastly, the crack paths obtained are compared with experimental data.
