Fatigue life estimation in welded joints under multiaxial loadings [PDF]
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 ...

Asynchronous Multiaxial Fatigue Damage Evaluation
Abstract One of the big challenges in fatigue characterization is to evaluate accumulated damage under asynchronous loading conditions. This multidisciplinary subject requires joining all multiaxial issues that are usually studied separately. Multiaxial fatigue models used in accumulated damage evaluation under random conditions are generally ...

Critical plane approach in stage i and stage ii of fatigue under multiaxial loading [PDF]
This paper deals with the estimation problem of the critical plane orientation in multiaxial fatigue failure criteria. Experimental results from multiaxial proportional, nonproportional cyclic loading and variable-amplitude bending and torsion were used ...

Multiaxial fatigue — An overview
Many engineering components are subjected to multiaxial type of fatigue loading and the fatigue life relation based on uniaxial testing needs modifications before it could be used for multiaxial condition. In this paper a brief review of the different approaches based on stress and strain is presented for the correlation of bulk parameters with the ...

A NEW MULTIAXIAL FATIGUE LIFE PREDICTION MODEL AND ITS APPLICATION (MT)
When mechanical components are subjected to multiaxial cyclic loading during operation, the additional strengthening effect is easy to occur. Using uniaxial fatigue life calculation formula to predict their life will produce large errors.
