Fatigue life prediction under mean stresses using critical plane approach
, 2023 Abstract This paper suggests that multiaxial fatigue criteria can serve as damage parametersin the formulation of critical plane theory. We propose that by incorporatingstrain rate effects, critical plane approximation parameters can be effectivelyused to estimate fatigue life under various test conditions.

Fatigue life estimation in welded joints under multiaxial loadings [PDF]
Fracture and Structural Integrity, 2009 Welded joints are frequently locations for cracks initiation and propagation that may cause fatigue failure of engineering structures. Biaxial or triaxial stress-strain states are present in the vicinity of welded joints, due to local geometrical ...
