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.
