Vibration fatigue

TL;DR: In this article, a nonlinear damage cumulative model for multiaxial high cycle fatigue based on continuum damage mechanics (CDM), which can incorporate the effect of welding residual stresses, is derived using FE technique.

TL;DR: In this article, the theoretical fatigue analysis of non-Gaussian random loadings is compared with theoretical estimations, and the results show how the load non-normality has a great effect on both the cycle distribution and the fatigue damage; the proposed method seems able to account for this effect correctly.

TL;DR: In this article, a non-linear dynamic analysis of the platform has been carried out for response calculations, and the response histories so obtained have been employed for the study of fatigue reliability analysis of TLP tethers under long crested random sea and associated wind.

TL;DR: In this article, fracture mechanics and damage mechanics were used to predict the fatigue lifetime for single lap joints with variable amplitude fatigue (VAF) loading. But, the results showed that a small proportion of fatigue cycles at higher fatigue loads could result in a significant reduction in the fatigue life.

TL;DR: In this paper, the authors proposed a band method for the evaluation of the fatigue behavior of mechanical systems and components subjected to random loads in terms of dynamic analysis and post-processing.
