Solutions are obtained, using constitutive equations of anisotropy creep theory and Norton's law, for a thick walled cylinder of an orthotropic material subjected to internal pressure. Expressions for stresses and creep rates are obtained under the assumptions (i) plane strain, (ii) generalized plane strain and (iii) plane stress. The results for plane strain case are compared with those obtained by Pai. It is shown that his conclusion that stress distribution was independent of anisotropic constants is not correct. The error appears to be due to simplified constitutive equations which has only one anisotropic constant used by him. The results indicate that creep anisotropy has a significant effect on the cylinder behaviour.
