A probabilistic model for the fatigue reliability of structures under random loadings with phase shift effects
S Lambert, E Pagnacco, L Khalij - International journal of fatigue, 2010 - Elsevier
A probabilistic model is proposed for the high-cycle fatigue reliability of structures subject to
multiaxial Gaussian random loadings with non-zero means. It is based on the Sines' criterion
combined with an oriented prismatic hull approach for its equivalent shear stress amplitude
J2, a in order to account for possible phase shifts between stresses involves in these
loadings. The extreme value distributions along the founded directions are efficiently
assessed in the frequency domain, from which we formulate the distribution of J2, a. This …
