Since for a specific type of material anisotropy described in the paper, these quantities are found to have the lowest values at the inner radius (the potential location of cylinder failure). Numerical results, presented through several graphs and tables, depict the effect of anisotropy on the stress, strain, and strain rate distributions. Using a threshold creep law for composite materials, expressions for stresses, strains, and strain rates are derived for several anisotropic cases.
