Display omitted •A modified generalized strain energy (MGSE) criterion for multiaxial fatigue analysis.•Comparative study on critical plane criteria for ductile/brittle materials.•Proposed MGSE criterion yields better predictions for ductile/brittle materials.•Modified SWT criterion provides accurate predictions only for brittle materials. This paper conducts a comparative evaluation on typical critical plane criteria, including Fatemi-Socie, Wang-Brown, modified Smith-Watson-Topper (MSWT) and proposed modified generalized strain energy (MGSE) criteria for multiaxial fatigue analysis of ductile/brittle materials. Experimental datasets of four materials under uniaxial tension, torsion and proportional/non-proportional multiaxial loadings are introduced for model comparison. This study results indicate that criteria with additional material constants yield robust life predictions for different materials. Moreover, the criteria with shear and uniaxial fatigue properties are respectively suitable for ductile and brittle materials, particularly the MGSE superior to others for ductile/brittle materials while MSWT only for brittle materials.
