This paper proposes a generalization of the Castillo and Fernandez-Canteli probabilistic fatigue model and shows how most fatigue models can be obtained as particular cases. Models that include mean stress effects and multiaxial loading conditions are considered as examples of this general framework. Several fatigue damage parameters such as the Smith-Watson-Topper, the Walker-like strain, energy based parameter in uniaxial and multiaxial loading conditions, and multiaxial critical plane parameters are proposed as reference parameters for the probabilistic model. It is shown that the Castillo & Fernandez-Canteli probabilistic approach can be successfully extended to these advanced fatigue models. (C) 2017 Elsevier Ltd. All rights reserved.
