Based on double superposition hypothesis, the displacement field of the laminated beam is established, which has fixed unknowns and satisfied the stress and displacement continuity conditions at interfaces. For simply supported composite laminated beams under general load forms, the equilibrium equations are changed into the algebraic equations by using Fourier series, and then the analytic solutions are obtained. All of the results are compared with 3D elastic solutions. The results are fairly satisfactory.
