Sažetak:
Prediction of failure of fracture toughness specimen is possible to estimate by using crack driving force and d5(CTOD)-R resistance curve of material. Accuracy of numerically determinated points on the curve of crack driving force depends on numerical model and description of mechanical properties of material. The appropriation of numerical model can be determined by comparision between numerical and experimetnal results for characteristic displacements. Initiation of stable crack propagation can be determined by deviation between numerically and experimentally obtained fracture behaviour curves. The intersection point between curve of crack driving force and d5 (CTOD)-R resistance curve provides the critical values of d5(CTOD) and crack extension, where the instability can be expected. The unstable fracture behaviour depends on hardening ability of weld metal and its volume in the weld joint.
