Differential equations are obtained for the inelastic deflections of long curved plates using small deflection theory. The usual assump¬tion of incompressibility of material (µ = 1/2) is avoided by making Poisson's ratio stress dependent beyond the elastic range. Buckling loads are obtained for both clamped and hinged edge conditions as¬suming a symmetrical mode typical of plates that buckle inelastic-ally. In addition, axial buckling solutions, more rigorous in terms of the variable Poisson's ratio, are obtained for circular cylinders and flat plates with clamped and hinged edge conditions.
