    Zafošnik, Boštjan ; Ulbin, Miran ; Flašker, Jože
    There are many methods for determination of stress intensity factors KI, KII. Evaluation of stress intensity factors determination using maximum energy release rate theory and complex J integral is ... the main purpose of the paper. Anumber of numerical analyses using the Compact Tension Shear (CTS) specimen were performed for determination of stress intensity factors. Virtual extension method (VCE) in framework the finite element method was used for crack propagation analysis. Calculated crack propagation angles with VCE method were compared to experimental results and crack propagation angles calculated using a maximum tangential stress criterion. Accuracy of determination crack propagation angles using virtual crack extension method was evaluated for different fracture mode.
