The effect of constraint level on a crack path
Original language description
The main aim of the work was to estimate the effect of a constraint on a predicted crack path and indicate cases where the failure of a component could be described more precisely by constraint-based description. Special specimen geometry with a high level of constraint was developed and numerical predictions of the crack path were compared with experimental results. The numerical model was built using commercial software ANSYS and a special procedure for the crack propagation was developed. The numerical prediction of the crack path based on a modified Maximum Tangential Stress (MTS) criterion (the criterion uses a two-parameter description of the stress field around the crack tip) is generally in agreement with the experimental data. The classical MTS criterion was found much more sensitive on the crack increment. Based on our numerical predictions it can be concluded that the modified MTS criterion predicted the crack path more precisely, especially in a case with high constraint le
