... with the conduction of resonant bending tests. A three-dimensional finite element model was developed to estimate the stress concentration on dented risers under bending. Numerical simulations and experimental tests were carried out to evaluate the resulting stress concentration factors (SCFs). These SCFs can be used...

... these connections. In this paper, analytical expressions for stress concentration factors for these connections are presented based on classical shell theory. The stress concentration is dependent on the radial restraint from the transverse plate and the eccentricity of the neutral axes in the tubular thickness...

... for. From contact with the industry, it is noted that there is uncertainty about the basis for the stress concentration factors (SCF) for conical connections in design standards for fatigue assessment. This is related to how fabrication tolerances are accounted for and how a transition in thickness from...

... stress from the analysis of one blow from all three phases at the weld location of interest. 5 Apply the stress concentration factor (SCF) relevant for the geometry at the weld. 6 Determine pile fatigue damage from pile driving phase based on the S-N curve E in air (for welds made from both sides...

... shake-down stress concentration factors Design S-N curves in design codes are based on fatigue test data, where the stress cycle is under external tension load. Due to residual stresses at weld toes, the same S-N curves are also being used in design standards for offshore structures when part...
