It is well known that the mechanical properties of laminated composites depend on the stacking sequences. As the bending modulus of elasticity is affected remarkably by the stacking sequences, the stress and strain analyses for laminated composite structures require a special technique. Therefore, a new analytical method has been proposed in order to calculate the mechanical behavior of laminated structures in this paper. The proposed method has been applied for a laminated composite structure as a numerical example. As a result, it has been recognized that the numerical behavior of the composite structure with anisotropic properties under mixed loads of bending and tension can be analyzed by the proposed method, even if it has two different moduli of elasticity of bending and tension. In addition, CPU time of FEM based on the proposed method can be reduced remarkably as compared with ordinary FEM.
