Abstract

In structures, which are free from RESIDUAL STRESSes, the STRESS INTENSITY FACTOR can be evaluated using the displacement extrapolation techniques. These numerical values are often in good agreement with the energy based calculations. In practice, the energy-based J-INTEGRAL is used for many structures as the appropriate fracture parameter or for the indirect calculation of the STRESS INTENSITY FACTOR. If the J-INTEGRAL is to be evaluated in presence of RESIDUAL STRESSes based on its original expression, the obtained integral will not be path independent. In this paper, a modified form of the J-INTEGRAL is used and its path independency is verified. The J-INTEGRAL is evaluated for two different geometries and the effects of various residual plus applied stresses are investigated.
