Service Handbook for the 2.75-in. Nalar Liquid-Propellant Rocket
Abstract
An explicit discrete beam solution based on the energy approach has been developed for simply and rapidly estimating the loading required to cause general instability of rectangular, cross-stiffened, flat-plated grillages whose edges are elastically restrained against rotation. A method for treating inelastic effects is presented both for materials which exhibit flat yield-type behavior and for those which show more pronounced strain hardening. Selected comparisons with more exact matrix methods indicate that in most cases, the accuracy of predicted elastic buckling loads can be expected to be within about 10 percent. Only when the number of transverse and/or longitudinal stiffeners is small and all four edges are highly restrained does there appear to be the possibility of larger discrepancies.
