Use the Fatigue Tool and set the Loading Type to Non-proportional Loading. 

The Non-proportional Loading option is a non-proportional constant amplitude loading type for models that alternate between two different stress states (for example, between bending and torsional loading). Problems such as an alternating stress imposed on a static stress can be modeled with this feature. Non-proportional loading is only supported for Fatigue Tool objects used with Solution Combination where you select exactly two stress states (only two Base Cases present in the Solution Combination Worksheet).
