    Abstract

    A simple procedure for the computation of buckling loads for simply supported rectangular curved sandwich panels is presnnted.The sandwich panels consists of centrally orthotropic aminated face sheets with isotropic or orthotropic core and are loaded with membrane loads parallel in the edges.the method is also valid for laminated composite panels without the sandwich core.The theory is augmented to include the effect of longitudinal stringers.The stringers are considered to be integral part of the panel and treated as an equivalent orthotropic skin and their stiffiness are smeared out fore adding it to the overall stiffiness of the panel.A simple computer program written based on the present method could be made use of for a quick and accurate estimation of bucking loads for laminated composite or sandwich panels
