Comparison between SSF and Critical-Plane models to predict fatigue lives under multiaxial proportional load histories

Comparison between SSF and Critical-Plane models to predict fatigue lives under multiaxial proportional load histories

Show other versions (1)

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 multiplies the hydrostatic or the normal stress...
