Anisotropy tensor of the potential model of steady creep

The Kelvin approach describing the structure of the generalized Hooke’s law is used to analyze the potential model of anisotropic creep of materials. The creep equations of incompressible transversely isotropic, orthotropic materials and those with cubic symmetry are considered. The eigen coefficients of anisotropy and eigen tensors for the anisotropy tensors of these materials are determined.
