A phenomenological approach, already used for other materials, is applied for the prediction of the behavior of 316 stainless steel under fatigue, creep or combined fatigue-creep loadings. The approach is based on the reduction of either the fatigue limit or the creep strength due to damage accumulation. For multilevel loading, an interaction parameter is introduced to account for the interaction effect between two different loading levels. Some particular aspects concerning the application of the procedure are discussed and the life predictions are compared with those obtained by some other techniques. The essential characteristic of the proposed approach is to provide a reasonably good prediction of life for the material subjected to the prescribed loadings using material constants which are determined through minimal experimental data.
