This report considers a thin spherical shell, the skin of which is made up of a number of uniform layers of different materials bonded together, and the stresses which occur therein as a result of a steady temperature gradient across the skin and internal pressure. After the metbod of stress calculation is outlined, numerical results are presented for aluminum shells covered by layers of various insulating materials. The results give an estimate of the magnitude of thermal stress which may occur in the skin of an insulated aircraft structure.
