Creep and plastic strains under side steps of tension and torsion for 304 stainless steel at 593/sup 0/C

OSTI ID:6685201
Results of nonproportional stress changes on creep and plastic strains resulting from abrupt changes in proportion of tension and torsion are reported. Both step-up and step-down changes are included. Constitutive equations based on data for single step creep and recovery tests previously reported are used to describe the test results. A viscous-viscoelastic model with aging effects and modifications for stepdown tests predicted the creep behavior reasonably well. The prediction of timeindependent plastic strains is also described.
