Thermal stresses are calculated in thick-walled circular cylinder under internal and external pressure. The concept of transition theory and generalized strain measures is employed for the creep analysis of thick-walled cylinder. The mathematical modelling details of the methodology applied in this analysis are discussed extensively. Analytical method of solution has been applied to simplify the governing differential equations. The obtained results are presented in terms of graphs. On the basis of analysis, it has been deduced that less compressible thick-walled circular cylinder with thermal effects under the influence of internal and external pressure with non-linear measure is a better alternative for design engineers as compared to other cylinders.
