Notes:
In this paper the rather complex 3D fatigue crack growth behaviour in a shaft with aquarter-circular crack under torsion is investigated by the aid of the programme ADAPCRACK3Dand by application of a recently developed 3D fracture criterion. It will be shown that thecomputationally simulated results of fatigue crack growth in the FE-model of the shaft are in goodagreement with experimental findings for the development of two anti-symmetric cracks, whichoriginate from the two crack front corner points, that is where the crack front intersects the freesurface of the cylindrical laboratory test-specimens. Consequently, also for this case with a rathercomplex 3D crack growth of two anti-symmetric cracks, the functionality of the ADAPCRACK3Dprogrammeand the validity of the proposed 3D fracture criterion can be stated
