概要

• 論文の詳細を見る

• This paper describes a new equivalent stress including the principal stress parallel to fatigue cracks based on COD concept and examines the applicability of that stress using a SUS 304 stainless steel at 823 K in air. Also the equivalent strain is derived from that equivalent stress using a continuum theory. Both the equivalent stress and the strain are proved to be good parameters to arrange the low cycle fatigue data in multiaxial stress state.
