### Abstract

The elementary theory of sandwich beams neglects the bending rigidity of the sandwich faces, or simply considers it as a small component of the total bending ridigity. This assumption usually does not cause any essential inaccuracy in the calculations. However, there are some engineering problems in which the elementary theory of sandwich beams proves deficient because of the above mentioned simplification. The paper presents the differential equations of buckling of sandwich columns with thick faces and a method based upon successive approximation to determine the critical load and buckling shape of columns subjected to an axial load distributed according to a polynomial function. The paper also presents a table for the calculation of the critical load of sandwich columns with various ratios of rigidities and subjected to uniformly distributed axial loads.
