The governing equations for laminated beams are developed by variational methods. The beams are considered to consist of n laminae and n-1 bond layers, where n can be any reasonable number greater than one. The bond thicknesses are assumed to be small in comparison with those of the laminae. The effects of shear strains and direct strains normal to the bending axis in the bond layers are included. Two specific problems are solved bending under uniform load and buckling of simply supported beams. Curves are presented which show the effect of bond flexibility.
