Abstract

The paper presents comprehensive design charts to be used for optimal selections of multilayered beams with elastic faces. Model deflections and bending were computed through the range of the geometrical and shear parameters which cover soft and stiff core materials. The results include the first three eigen frequencies for four combinations of end conditions of interest in bridge, space-craft and machine designs. The computer aided investigation considered the relative merits with respect to the simple homogeneous beam.
