-The path independent integral, _( is presented as the rate of energy flux during crack extension. This integral is an extension of the J-integral proposed by Rice and includes the existence of a fracture process region and the effect of plastic deformations, body forces, thermal strains and inertial of material. It isshown that the j-integral can include as special cases other fracture mechanics parameters such as J by Rice, G by Eftis et al., /* by Blackburn or f by Strifors.
A definition of the j-integral in a three-dimensional problem is presented and possibility of applying the ./-integral as fracture criterion is discussed.

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 an
