Description	Fatigue crack propagation in ferrite (bainite) near the austenitic cladding was modelled by means of the elastic-plastic finite element method and the effect of the bi-material interface on the cyclic plastic zone size and shape was investigated. It was demonstrated that cyclic plastic strains in softer austenite are already present at the moment when the cyclic plastic zone around the crack tip in harder ferrite reaches the interface. Crack tip plastic zones under plane stress and plane strain conditions vary in size and shape and are affected by the approaching material interface. The level of dissipated energy in front of the fatigue crack and, therefore, the crack rate increased as the boundary of the cyclic plastic zone reached the material interface.
