## A cumulative damage theory is developed based on the concept of bounds on residual life. Previous results applicable to fatigue are generalized to creep-rupture and to creepfatigue interaction. By defining a creep endurance limit and void-initiation life fractions, a complete symmetry is establ

In the following, some of the concepts discussed before afie assessed with respect to their ability to predict fatigue lives under variable amplitude loading. Typical trends of results are outlined.
