Mechanical Engineering Department, Indian Institute of Technology, Powai, 400 076, Bombay, India aut Finite element computation of the strain energy release rate for kinking of a crack [Elektronische Daten] [S. Maiti] The approximate energy release rate for a crack which extends, or "kinks”, away from its original direction has been computed by finite element analysis using three different methods: stiffness derivative procedure, J integral method and crack closure integral procedure. A case study is presented to compare the computational accuracies. It suggests that a satisfactory approximation can be obtained provided that the ratio of kink length to original crack length, l(0)/a⩽0.04, despite the interaction of the crack tip and knee stress singularities.
