中文摘要	A multilayered shell element with relative degrees of freedom is presented for thermal and mechanical analyses of composite laminated structures. The analyses can be performed using the same finite element mesh. The 2-D element is based on 3-D FEM and can be easily connected with a 3-D solid element. A post-processing method was used to compute the transverse stresses in composite shells of revolution. The validity and accuracy of the program are shown by two numerical examples analyzing a composite cylindrical shell with a cutout and a reinforcement around the cutout. The results show that large interlaminar stresses occur around the cutout when there is distinct mismatch between the thermal expansion coefficients of the reinforcement and the skin, which may cause delamination.
