Abstract:

A method for determining the optimum dimensions of straight, circular, cylindrical, transversely stiffened sandwich shells having cores made of a shell material corrugated in saw-tooth form is proposed. A shell of a given outer radius, length, and elastic characteristics of the material is subjected to a uniform compression load. The optimum values of the following unknown parameters have to be determined. Core parameters saw-tooth height, pitch, and sheet thickness thickness identical of the face layers distance between equally spaced identical transverse frames and their moment of inertia and buckling stress.
