ELASTIC BUCKLING OF TWO-LAYER CYLINDERS AND CURVED PLATES,

Abstract

It is shown that the Donnell equation of a thin cylindrical element composed of two well-bonded layers of different materials but which have equal Poisson ratios is identical in form to the single-layer equation except in the stiffness constants. It is possible then to utilize the results of single-layer buckling analyses for cylinders and curved plates by proper substitution of the bending and extensional stiffnesses of the two-layer wall for the corresponding stiffnesses of the single-layer wall. The case of the cylinder in axial compression is discussed in some detail. (Author)
