The Influence of Constraint Level on Crack Path
Original language description
The main aim of the work was to estimate effect of the constraint on the predicted crack path and show the cases where the failure of the component could be described more precisely by constraint-based description. A special specimen geometry with a highlevel of constraint was used. Numerical predictions of the crack path in a modified CT specimen are compared with experimental results. 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. It can therefore be concluded, that themodified criterion in the framework of two-parameter linear elastic fracture mechanics estimated the crack path more precisely only in the case of a high level of constraint.
