Abstract
The finite element method was applied to generation phase analyses for stable crack growth in inhomogeneous materials. Experimental data on stable crack growth in bimaterial CT specimens, which were composed of a base metal and a weld metal, were numerically simulated using the n ode-release technique, and the variations of the fracture mechanics pa rameters such as the J-integral, T-integral, J-integral and CTOA were calculated. The effects of the fusion line and the weld material on t he near-crack fracture mechanics parameters were discussed.
