Abstract: | The problem of simplifying the nonlinear hereditary elasticity relations is considered for strongly anisotropic materials
such as fiber-reinforced composites. This is done using their property that the material stiffness is high along the reinforcement
and is low in the cross-sectional direction. The material is considered transversally isotropic. The simplification is performed
by analyzing asymptotic representations of creep relations. Relations of various degrees of accuracy for various types of
composites and stress states are obtained.
