Název v původním jazyce

Fuzzy probability analysis of the fatigue resistance of steel structural members under bending

Popis výsledku v původním jazyce

The paper is aimed at the fuzzy probabilistic analysis of fatigue resistance due to uncertainty of input parameters. The fatigue resistance of the steel member is evaluated by linear fracture mechanics as the number of cycles leading to the propagation of initial cracks into a critical crack resulting in brittle fracture. When the histogram of stress range is known, the fatigue resistance is a random variable. In the event that the histogram is unknown or was acquired from a small number of experiments,another source of uncertainty is of an epistemic origin. Two basic approaches, which make provision for uncertainty of input histograms of stress range, are illustrated in the paper. Uncertainty of histograms of stress range is taken into account by thevariability of equivalent stress range in the first stochastic approach. Input histograms as considered as members of a fuzzy set in the second approach.
