Comparison between SSF and Critical-Plane models to predict fatigue lives under multiaxial proportional load histories [PDF]
Fracture and Structural Integrity, 2016 Materials can be classified as shear or tensile sensitive, depending on the main fatigue microcrack initiation process under multiaxial loadings. The nature of the initiating microcrack can be evaluated from a stress scale factor (SSF), which usually ...

Comparative study of multiaxial fatigue methods applied to welded joints in marine structures [PDF]
Fracture and Structural Integrity, 2016 Marine structures are particularly prone to action of waves, winds and currents with stochastically varying composition, intensities and directions. Therefore, resultant stresses may cause multiaxial fatigue in specific welded structural details. For the
