Abstract


The authors present an analytical solution for two-layered composite beams with interlayer slip. Timoshenko's kinematic assumptions are used for both layers imposing the constraint of the equal cross-sectional rotations. The connection between the beam components is perfect in normal direction, but the axial displacement field may have a jump. The axial force derived from the imperfect connection is proportional to the relative slip occurring between the layers. The determination of the analytical solution of the considered static problem is based on the fundamental solutions. Linear combination of the fundamental solutions, which are fitted to the given loading and boundary conditions, gives the total solution. Three examples illustrate the applications of the presented analytical method.
