Creep and plastic strains under stress reversal in torsion with and without simultaneous tension for 304 stainless steel at 593/sup 0/C

OSTI ID:6706485
Results of creep experiments under stress reversals in torsion with and without constant tension are reported. Constitutive equations based on data for single step creep and creep recovery tests previously reported are used to describe the test results. A viscous-viscoelastic model with aging effects and modifications for stepdown stress changes and stress reversals predicted the creep behavior reasonably well. The prediction of time-independent plastic strains is also described.
