The kinematic hardening rule formulated in the first report of this work is applied to ratchetting experiments of Modified 9Cr-1Mo steel by Tanaka et al. and nonproportional tests along cruciform and circular strain paths. It is shown that this rule is capable of predicting much less accumulation of ratchetting strain under uniaxial and multiaxial loadings than the Armstrong and Frederick rule ; however, if ratchetting strain is negligible, these two rules may give nearly the same predictions. Burlet and Cailletaud's modification of the Armstrong and Frederick rule is also discussed.
