  • A synthetic analysis is made for the probabilistic models of cyclic strain-life relations of 16MnR steel weld joint. Purpose aims to employee synthetically the test data under different test conditions, which could reflect the production environments, to provide the reasonable curves for fatigue reliability design and analysis of the material and structures. The models are constructed with the probabilistic three-parameter exponent relations. They consist of the survival probability-based strain-life curves, the confidence-based strain-life curves, and the survival probability and confidence-based strain-life curves. These curves could provide a wide advice for the fatigue probabilistic design and analysis of the material and structures. Parameters of parent metal are also provided to make a comparison between weld joint and parent metal.
