Abstract
Abstract The crack growth life assessment procedures at high temperature developed for isotropic materials need to be extended for anisotropic creeping materials. In this study, estimation of C t in transversely isotropic creeping materials is proposed. Equivalent creep coefficient ( A eq ) is defined for the transversely isotropic materials and its calculation equation is derived in terms of the ratio between the longitudinal and the transverse creep coefficients. A series of finite element analysis was conducted and values of correction factors required in calculating C t were determined in tabular form. The newly proposed equation gave the same C t values as the finite element results under the full range of the creep conditions including the small scale creep.
