Resumen de Kinematic hardening rules with critical state of dynamic recovery, Part II: Application to experiments of ratchetting behavior

J.-D. Wang, N. Ohno

• The kinematic hardening rules formulated in Part I of this work (i.e, Models I and II) are applied to ratchetting experiments of Modified 9Cr-1Mo steel done by Tanaka et al. as well as to a nonproportional experiment of OFHC copper by Lamba and Sidebottom. It is shown the Models I and II have the capability of simulating ratchetting behavior well because they can predict much less accumulation of ratchetting strain under uniaxial and multiaxial loadings than the Armstrong and Frederick model. It is also shown that if ratchetting strain is negligible, Models I and II may give nearly the same predictions as the Armstrong and Frederick model.
