An improved strength model is developed for predicting creep rupture under multiaxial stress states. The new model incorporates four stress parameters and distinguishes between life under tensile versus compressive stress states. Assessments of the new model based on experimental biaxial creep-rupture data for type 304 stainless steel tested at 593/sup 0/C show the new model to be significantly more accurate than the classical criteria of Mises, Tresca, or Rankine.
