Sažetak
In this paper, the influence of weldment heterogeneity is of primary interest and will be analyzed both theoretically and numerically. Theoretical analysis is applied in order to show that the J integral is not path independent for a generally shaped weldment. However, its path independence can be recovered if the modified J integral is introduced, comprising the original J integral and line integrals along weldment interfaces. Toward this end the modified J integral for multi-material body, representing welded joint with four different material regions (base metal - BM, weld metal - WM, coarse grain heat affected zone - CGHAZ and fine grain heat affected zone - FGHAZ)is defined.
