This paper is concerned principally with the basis for the formulation of a creep model that represents creep data of metals sufficiently accurately and that lends itself to numerical stress analysis of creep under multiaxial states of stress. A phenomenological approach is taken. Several forms of creep relations and flow conditions for multiaxial creep are considered. Comparisons of analytical predictions with experimental results are shown. Recommendations for numerical stress analysis of creep in engineering machines and structures subject to multiaxial stress states are given, and a promising technique for collection of the voluminous data that result from numerical stress analysis is indicated. An extensive reference list is included.
