摘要：

In this paper the rather complex 3D fatigue crack growth behaviour in a 3PB-specimen with an inclined plane of the initial crack or notch 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-model of the specimen are in good agreement with experimental findings for the development of the spatially twisted crack faces in the real laboratory test-specimen. Consequently, also for this case with a rather complex 3D crack growth behaviour, the functionality of the ADA-PCRACK3D-programme and the validity of the proposed 3D fracture criterion can be stated.
