Abstract |
The behavior of anisotropic laminated structures is quite different from that of isotropic ones. Also, the classical theory of shells, based on neglecting transverse shear deformation, is invalid for laminated shells. Thus, to obtain the more exact behavior of laminated shells, effects of shear deformation should be considered in the analysis. As the length of x-axis or y-axis is increase, the effects of transverse shear deformation are decrease because the stiffness for the axis according to the increasing of length is large gradually. In this paper, the governing equations for anisotropic laminated shallow shell including the effects of shear deformation are derived. And then, by using closed-form solutions for shallow shells having simple supported boundary, extensive numerical study for anisotropic laminated shallow shells was made to investigate the effects of stacking sequence and shear deformation for cylindrical shells. Also, static analysis is carried out for cross-ply laminated shells considering the effects of various geometrical parameters, e.g., the ratio of length-to-radius, length-to-thickness and a(length of x-axis)-to-b(length of y-axis). The results are compared with existing one and show good agreement. |
