THE STABILITY UNDER LONGITUDINAL COMPRESSION OF FLAT SYMMETRIC CORRUGATED-CORE SANDWICH PLATES WITH SIMPLY SUPPORTED LOADED EDGES AND SIMPLY SUPPORTED OR CLAMPED UNLOADED EDGES

摘要

A theory for the elastic behavior of orthotropic sandwich plates is used to determine the compressive-buckling-load parameters of flat sym¬metric corrugated-core sandwich plates with simply supported loaded edges;and simply supported or clamped unloaded edges. Charts are presented for corrugated-core sandwich plates for which the transverse shear stiff-ness in planes parallel to the axis of the corrugations may be assumed infinite. The limits of validity of this assumption are investigated for simply supported plates.
