PROBABILISTIC MODELS OF UNCERTAINTIES IN FATIGUE AND FRACTURE RELIABILITY ANALYSIS

摘要

Probabilistic methods enable the modelling of the uncertainties associated with the integrity assessment of structures containing defects to be taken into account. This paper presents a critical review of recent developments in the probabilistic modelling of the uncertainties associated with fatigue and fracture reliability assessment. A number of probabilistic models for the principal parameters in the S-N curve, fatigue crack growth functions and fracture analysis are presented and discussed with particular emphasis on the identification of future needs for the development of suitable code procedures for offshore structures.
