A study of use deterministic fatigue life prediction methods for a set of multiaxial experimental data on broad-band random loading to a tubular specimen with a hole is presented. There is a discussion of the applicability of stress-based predictions and strain-based predictions based on the linear cumulative rulke under current conditions. The only feasible criteria finally chosen for the application are strain-based methods for analysing the fatigue life until fatigue crack initiation.Several methods differing in the damage parameter and application of the mean stress effect are evaluated.The results are presented, and the most promising method (by Erdogan and Roberts) has been selected.
