✦ 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.

In this paper, a quadratic polynomial expression is used as the displacement shape function to develop the Boundary Contour Method. In this work, the divergence free property of the J integral is proved; the evaluation of the J integral is transformed, through an application of Stokes' theorem, into
