Abstract
In the ASME Code, Section III NB-3228.4(c) requires that if an elastic-plastic fatigue analysis is performed, the fatigue curve shall be entered with the numerically maximum principal total (elastic plus plastic) strain range multiplied by one-half the modulus of elasticity of the material at the mean cycle temperature. This paper discusses the choice of the principal strain range as well as other possible strain range measures for elastic-plastic fatigue analysis. Several generic observations that form the basis for the discussion are outlined.
