Abstract : For rotational shells, approximation theories may be derived for the threedimensional elasticity theory that permit approximation to any desired degree of the threedimensional theory, and make it possible to establish the extent to which the equilibrium conditions in unit volume and the basic equations of the elasticity theory are fulfilled. In the derivation of these approximation theories, it was assumed that the stresses and the shifts in the power series can be developed according to the coordinate that is perpendicular to the center surface, that the elasticity theory is applicable, and that the materials are homogeneous and isotropic. The order of the shell equations and the number of members in the power series for the dislocations and stresses are then obtained as functions of the exponent of a parameter that characterizes the relations between half the shell thickness and an appropriate length. (The exponent determines the degree of approximation of the threedimensional theory). A circular cylinder shell is considered under axisymmetric load and in the plane stress state. (Author)
