Abstract: The shear force expression of sandwich beam section under external load is derived, and the strain energy function of sandwich beam during bending is written by using the stress expression of sandwich beam section. The strain energy function is partial to the concentration to obtain the bending deflection of sandwich beam at a concentrated force point. The results show that the energy method has a high accuracy in calculating the bending deflection, and the experimental results are in good agreement with those of related literature.
