Deformations in balanced laminated shells of revolution, subjected to internal pressure and thermal loads, are investigated for a special case of spherical composite shells, using the membrane theory. It is shown that the membrane theory is able to predict the deformed shapes of laminated shells with identical longitudinal and transverse stiffnesses, when subjected to internal pressure and thermal loads. For other laminates, such as (0 sub 8)T and (90 sub 8)T, which have unequal axial and transverse stiffnesses, the membrane theory did predict unbounded deformation about phi = 0; for such laminates, the stress buildup about phi = 0 could not be balanced with membrane forces alone. 7 refs.
