Vibration fatigue

TL;DR: Wei et al. as discussed by the authors presented a new path-dependent multi-axial fatigue damage model which is formulated based on an incremental form of Moment of Load Path (MLP) on either σ - β τ stress plane or e - β e γ strain plane.

TL;DR: In this paper, the dependence of fatigue damage accumulation on power spectral density (psd) is investigated for Gaussian random processes representing stresses in offshore structures, which involves extensive computer simulation of representative stress time histories and related analyses to predict the time of fatigue failure.

TL;DR: In this paper, a new equivalent stress that can be used as a uniaxial stress time history suitable for the application of damage evaluation methods has been developed, which is not accepted by the majority of researchers because a definition in agreement with experimental results has not been found yet.

TL;DR: In this article, a semi-empirical method for time domain simulation of vortex-induced vibrations (VIV) is used to calculate the in-line and cross-flow fatigue damage of a tensioned riser in uniform and sheared flow.

TL;DR: In this article, the authors investigated the fatigue behavior of local structural assemblies under loadings that differ from the fatigue test loading in magnitude or in statistical distribution, or after a local change in structural sizes or design, stress concentrations m critically loaded assemblies are considered.
