Can Keff be assumed as the driving force for fatigue crack growth? [PDF]
Fracture and Structural Integrity, 2015 This work raises some new questions about the validity of blindly assuming that Elber’s effective stress intensity factor is the actual fatigue crack driving force, and that as so it can be used to explain all load sequence effects on fatigue crack ...

Growth of inclined fatigue cracks using the biaxial CJP model [PDF]
Fracture and Structural Integrity, 2015 The CJP model of crack tip stresses is a modified version of the Williams crack tip stress field which takes account of simplified stress distributions that arise from the presence of a zone of plastic deformation associated with the crack flanks and ...

Hydrogen-Accelerated Fatigue of API X60 Pipeline Steel and Its Weld
Metals, 2023 In this work, the hydrogen fatigue of pipeline steel X60, its girth welds and weld defects were investigated through in situ fatigue testing. A novel in situ gaseous hydrogen charging fatigue set-up was developed, which involves a sample geometry that ...

The effect of grain size on the fatigue overload behaviour of nickel
Materials & Design, 2020 The fatigue overload behaviours of coarse grain (~30 μm), ultrafine grain (360 nm) and nanocrystalline (~30 nm) Ni are compared under constant amplitude loading at R = 0.1 after a 100% overload. Synchrotron X-ray diffraction is applied to map the elastic
