000001426 520__ $$2eng$$aA 3D elastic-plastic FEM model with small strains was used for simulation of the deformation mechanics at the curved front of the planar fatigue crack growing in the thick CCP specimen. The results show that the crack front behaviour depends not only on the local effective stress intensity factor range but also on the local level of constraint. The stress and plastic strain cycle in very thin surface layer is qualitatively similar to the plane stress. The rest of the front is exactly in the plane strain state. The plane of the absolute maximum shear stress corresponds to the shear lip plane at the end of the crack front.
