Fatigue Crack Growth Simulations and Experimental Findings for SEN-Specimens under Different Loadings
In this paper the rather complex 3D fatigue crack growth behaviour in a SEN-specimens under anti-plane shear or torsion loading is investigated by the aid of the programme ADAPCRACK3D and by application of a recently developed 3D fracture criterion. It will be shown that the computationally simulated results of fatigue crack growth in the FE-models of the specimens are in good agreement with experimental findings for the development of two antisymmetric cracks, which originate from the two crack front corner points, that is where the crack front intersects the free surfaces of the laboratory SEN test-specimens. Consequently, also for these cases with a rather complex 3D crack growth of two anti-symmetric cracks, the functionality of the ADAPCRACK3D-programme and the validity of the proposed 3D fracture criterion can be stated.
