This paper presents a probabilistic method for fatigue life estimation within the
frequency domain for structural elements subjected to multiaxial random loadings.
Multivariate Monte Carlo Simulation is used to account for the correlation between the
stress components and their different probability of occurrence and, moreover, enables
stochastics during damage analysis to be allowed for and, at the same time, uses any
suitable, material dependent multiaxial fatigue criterion known from the time domain.
Comparison of the evaluated fatigue damage with experimental results from vibration tests
on a demonstrator, chosen from common application fields in the automobile industry, shows
good correlation.
