| Abstract: | Spline finite-layer method based on three-dimensional displacement assumption is applied in bending analysis of isotropic or anisotropic plates and cylindrical shells, the displacement of layer element is supposed to distribut linearly along the thickness. According to minimum potential energy principle, basic equations of spline finite-layer method can be established. Numerical results show that proper solutions can be gained with less nember of joints and layer elements, also, it has advantages such as suitability for either plates or cylindrical shells. |
