Abstract

Two simplified methods for determining multiaxial relaxation and creep damage, the GLOSS time-scaling and the ASME Code Case N-47 method, are described in this paper. The theoretical basis and applicability of the methods to various pressure component configurations are discussed in detail. The G -factor in the ASME formula in effect speeds up or slows down the uniaxial relaxation process, similar to the GLOSS time-scaling method. The two methods are compared, and the differences are attributed to local follow-up not being accounted for in the ASME formula.
