✦ Synopsis
The equation for evaluating the nonlinear fracture mechanics parameters J-and jintegrals are derived using the virtual crack extension method. The validity of the equations derived here are checked by solving several numerical examples, that is, the J-integral analyses of compact tension specimen and three-point bend specimen, and the j-integral analysis of centrally cracked plate. Reasonably good agreement is found between the virtual crack extension method and the line integral method.
