“…The initiation of cracks would appear at base metal, weld metal, fusion zone or the interface of different materials [3]. The material properties are different at different position in dissimilar weld joints, and the different constraint effect induced by mechanical heterogeneity will lead to the discontinuous of stress and strain distribution nearby crack tip, and affect the fracture behavior of dissimilar weld joints [4]. The fracture mechanics parameters based on homogeneous materials are unsuitable under the affect of strength mismatch of materials nearby crack tip, and the fracture mechanism is also unsuitable for predicting the crack propagation in heterogeneity materials.…”

The propagation behavior of crack with different initiation position is affected by the constraint effect differences in dissimilar weld joints mechanical heterogeneity. The ductile fracture model of interface crack in dissimilar weld joints was built by adopting extended finite element method; the propagation characteristic of interface crack was summarized. The results indicate that the strength mismatch of materials at sides of interface will increase trend of crack advancing into the relative soft material which has lower yield strength and lower hardening exponent.

The crack growth behavior in dissimilar weld joints is affected by the mechanical heterogeneity of materials. The subcritical crack growth in dissimilar weld joints was simulated by adopting extended finite element method. The results indicated that the strength mismatch will affected the subcritical crack growth behavior. The growth direction of subcritical crack in material with higher strength will deviate to the interface, and the crack may advance through the interface to material with lower strength if the strength mismatch is critical. The cracks will advance away from the interface if the subcritical crack in soft material.
