On one model of anisotropic creep of materials

The concept of proper modules and the states, revealing the structure of generalized Hooke's law, is applied to one model of the anisotropic steady-state creep of materials. The steady-state creep equations of incompressible materials are presented in an invariant form. The matrix of anisotropy coefficients of these materials is reduced to block form with nine independent components. The special case of an ortotropic incompressible material is considered for which the matrix of anisotropy coefficients corresponds to a nonor.
