Effect of Face-Sheet Stiffness on Buckling of Cylindrical Shells of Sandwich Construction

Abstract

Results are presented for the effect of flexural stiffness of face sheets on the buckling of elastic cylindrical sells of sandwich construction subjected to axial and lateral loading. This study shows that when the core is very weak in shear the flexural stiffness of the face sheets can significantly increase the buckling load. This increase is shown to be much larger for axially loaded shells than for laterally loaded ones. Graphical results are given for a wide range of the significant parameters. The results are based on a linear buckling theory for sandwich shells of the Donnell type, which takes into account the asymmetry of the sandwich faces.
