Abstract: The problem of a transversally isotropic, circular, cylindrical shell subjected to periodically spaced, axisymmetric band loads is investigated. The three-dimensional elasticity solution is obtained and stresses and displacements are evaluated for values of the modulus ration (Er/Ez) equal to two, five, and ten. Expressions for the stresses and displacements obtained by use of a thin orthotropic shell theory are also presented. These results are compared to determine the effects of a change in modulus ratio on the stresses and displacements of the cylinder and the accuracy of the shell theory. A detailed analysis of the data is performed for a ratio of inner to outer shell radii equal to 0.70, a ratio of distance between band loads to outer shell diameter equal to 0.2, and a ratio of band width to distance between band loads of 0.2.
