A two-parameter model for fatigue strength estimation of high-strength steels in very-high-cycle-fatigue regime

open access: yes, 2013
A model containing two microscopic parameters, i.e. inclusion size and fine granular area size (FGA) is proposed for the estimation of fatigue strength or S-N curve of high-strength steels with fish-eye failure mode for very-high-cycle-fatigue (VHCF ...
