Results of a buckling test of a 10-foot-diameter 3-m truss-core sandwich cylinder loaded in bending are presented. The cylinder failed as a result of the growth of wall buckles some of the buckles existed as initial imperfections in the cylinder wall prior to testing. Failure occurred suddenly at a load corresponding to approximately 62 percent of the load computed with the use of classical small-deflection buckling theory.
