ESDU 68033
Buckling loads under combined longitudinal and transverse direct stress of flat sandwich panels. (Isotropic face plates and corrugated cores, all edges clamped.)
Abstract:
The elastic buckling loads are presented graphically in terms of the overall dimensions of the panel and its flexural and transverse through-the-thickness shear stiffnesses. The data are applicable to sandwich panels with cores having a shear stiffness through their thickness which is very much higher along the corrugations than across them. The panel length to width ratios covered are from 0.6 to 5.0 (approximately) and infinitely long panels. See ESDU 68029 for the background to the theory and for calculations of sandwich panel stiffnesses. See ESDU 81047 and ESDUpac A8147 or ESDU 94005 and ESDUpac A9405 for a computer program for calculation of buckling load.Indexed under:
