The applicability of a non-linear Fatigue Damage Function for multiaxial fatigue strength prediction is verified for various metallic materials including mild steel, hard steel, cast iron and aluminium alloys. The proposed method determines the orientation of the critical plane which experiences the
The interaction between creep and fatigue has been studied theoretically by considering a macroscopic crack, interacting with continuously distributed microdamage. This damage is a measure of an assumed deterioration of the material. A Dugdale crack model is used with most deformation and damage con
## 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
