Abstract : An energy principle is employed to derive the equations governing the stability of a simply-supported, eccentrically ring-stiffened, oval, orthotropic cylindrical shell. The kinematic equations are those of Love-type shell theory and the effect of the reinforcing rings is accounted for by a distributed stiffness approach. The cylinder is subjected to a combination of uniform lateral and axial pressures. It is determined that the domain of stability of a stiffened cylinder is bounded by two separate solutions denoted as 'long' and 'short' axial wavelength solutions, the extent of the short wavelength solution being dependent upon the degree of stiffening afforded by the rings.
