This study deals with bending analysis that takes into account the slipping displacement at the joint surfaces of composite cross-section beams with arbitrary cross-sectional shapes, arbitrary material properties, and arbitrary number of joint surfaces. In this paper, the analysis method to take into account the effects of shear deformation are developed. In this paper, the following points are clarified.
1. A finite element analysis model is proposed for Timoshenko beams with any cross-sectional shape, any material properties, any number of layers at the joint surfaces, and any adhesion coefficients at the joint surfaces.
2. Several numerical analysis examples are carried out, and it is shown that the proposed analytical model is effective.
3. An elastic analysis method that evaluates shear deformation by taking into account the effect of sliding displacement on the joint surfaces of laminated beams is presented.
