Abstract

A review of a theoretical and experimental program on the buckling behavior of sandwich cylinders is presented. The two types of instability which can occur for a sandwich element are considered. One type involves buckling of the sandwich element as a unit and the other is concerned with the buckling of the faces upon the core which is commonly referred to as wrinkling. Both types are considered theoretically for the sandwich cylinder under compressive and torsional loadings. Experimental data on buckling loads and buckle patterns are offered to substantiate the theoretical results.
