Abstract : A solution is presented for the thermal stresses in an isotropic, homogeneous, viscoelastic, hollow cylinder enclosed by a rigid casing. The governing equation, which is of the integral-differential form, is integrated numerically. The resulting partial differential equation is solved exactly subjected to the imposed boundary conditions. For comparison, a simple four-parameter viscoelastic material is chosen since an independent analytical solution is available. A second example is presented in order to demonstrate the capability of this solution in handling large numbers of viscoelastic parameters which are usually required to characterize real solid propellant and other polymeric structural materials.
