摘要

•Detailed phylogeny of strain energy density (SED) in fatigue modelling.•Total SED (TSED)-based life formula with two power function terms.•Guiding flow to determine the (axial) SED-related material fatigue parameters.•Better fatigue data correlation of TSED than the strain-based CMB equation.•Solution for the standardized application of TSED-based model in fatigue analysis.
