Berücksichtigung der Dehnungsbehinderung in bruchmechanischen Sicherheitsanalysen
… Concerning upper shelf behaviour and ductile crack initiation, a physical as well as a technical characteristic value of the critical crack tip loading J can be employed. But, as the stress-state is changing due to crack growth there is a certain influence on the result of the fracture …

Fatigue crack growth in hydrogen pipeline steels
… mechanism is hydrogen accelerated fatigue crack growth since it is well known that hydrogen can enhance fatigue crack growth rates by a factor of 10. In this thesis, the fatigue life of a line pipe manufactured with API steel is calculated by investigating the growth of a semi-elliptical …

Quantifying the Constraint Effect of Three-Dimensional Specimens with Biaxial Loading Using the J-A2 Method
… integrity of mechanical components containing cracks. Often, the fracture toughness depends upon the geometry of the component as well as the configuration and level of the applied loading. This dependence is referred to as the constraint effect in fracture. The two parameter J-A2 method is …

Fatigue growth of surface flaws in finite plates
… observed structural defect is the surface crack. The primary difficulty in analyzing the growth of surface cracks is the stress intensity factor which varies from point to point along the crack due to crack front curvature and the complex local geometry. The study of surface cracks started …
