Probabilistic life prediction of mechanical system components requires the modeling of multiple complex random phenomena. This paper develops a simulation-based stochastic approach for this purpose, using loading history and material properties as basic uncertain quantities. The interaction effect between different fatigue loading levels and between fatigue and creep are considered. The loading sequence effect is considered during the procedure of damage evaluation. Probabilistic fatigue and creep life prediction for a generic aircraft jet engine blade is illustrated through a numerical example.
