N2 - An experimental technique for analyzing the crack propagation stability of single edge notch specimen is discussed. The testing rig and its calibration procedure are described. Analyzed are the crack path under biaxial loading and its correlation with theoretical predictions. The mode II influence on the crack path is also presented. Use is made of the computer program ANGCRK. Fracture criteria are applied to determine the stability of crack growth. Stability is assumed to prevail when the second term of the eigenfunction series expansion is negative. Otherwise, the crack growth could be unstable.
