摘要：

In this paper, the rather complex three-dimensional (3D) fatigue rack growth behaviour in a single-edge notched (SEN) specimen with an inclined plane of the initial crack under torsion loading is investigated with the aid of ADAPCRACK3D programme and by application of a recently developed 3D fracture criterion. It will be shown that the computationally simulated results for fatigue rack growth in the FE model of the specimen are in good agreement with experimental findings for the development of spatially twisted and warped rack faces in the real laboratory test specimen. Consequently, also for this case with a rather complex 3D crack growth behaviour, the functionality of the ADAPCRACK3D programme and the validity of the proposed 3D fracture criterion can be stated.
