Abstract
Donnell's equation for thin-walled circular cylinders is replaced by where w is a non-dimensional form of the radial displacement and q is the distributed radial loading. This equation retains the essential simplicity of the original but, unlike Donnell's equation, the accuracy does not decrease as the wavelength of circumferential distortion increases.Keywords
