Abstract : Results of buckling tests on three honeycomb sandwich cylinders loaded in bending are presented and discussed. In addition, analytical studies are made on (1) the influence of the core and bonding material in enhancing the stiffness of composite sandwich plates like those of the walls of the test cylinders and on (2) plastic buckling of sandwich cylinders in compression. Results of the two studies are compared with observed behavior of the test cylinders. The bending stiffness of the test cylinders correlated well with predicted behavior. Buckling of the test cylinders occurred at lower loads than predicted by theory by about the same margin that would be suggested by an extrapolation of the results of buckling tests on conventional thin-wall cylinders.
