Evaluation of new multiaxial damage parameters on low carbon steel [PDF]
Fracture and Structural Integrity, 2017 Most mechanical components are subjected to the complex fatigue loading conditions, where both amplitude and direction of loading cycles change over the time. The estimation of damage caused by these complex loading scenarios are often done by simplified

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 ...

Life estimation by varying the critical plane orientation in the modified Carpinteri-Spagnoli criterion [PDF]
Fracture and Structural Integrity, 2015 The modified Carpinteri-Spagnoli (C-S) criterion is a multiaxial high-cycle fatigue criterion based on the critical plane approach. According to such a criterion, the orientation of the critical plane is linked to both the averaged directions of the ...
