Abstract This study investigated the application of the life-dependent material parameter concept to stress-based fatigue criteria for fatigue life prediction under multiaxial variable-amplitude loading. Different multiaxial fatigue criteria were applied to the fatigue life calculation with fixed and life-dependent material parameters under constant- and variable amplitude loading. Uniaxial variable-amplitude loading was applied to select the appropriate damage accumulation rule. The verification was based on experimental tests with 133 specimens made of S355 steel. Significant improvements in the fatigue life prediction under both constant- and variable-amplitude loading were observed with the applied concept.
