A method for determining the optimum configuration of flat, simply supported sandwich panels under uniaxial compression. It is assumed that the load, width, and stress-strain curves for the face material are given, with side conditions on the maximum allowable face stress (or strain) and on core strength or density. Application to square- and hexagonal-cell honeycomb core panels is shown, and elevated temperature effects are discussed.
