| Abstract: |
| In this paper,the unequdistant B_3-spline function is used for establishing the meridional and circumferential shape function,and the circumferential shape function satisfies the periodic condition. The generalized spline subdomain displacement mode is got by interpolating in the longitudinal direction firstly and then in the circumferential direction. The method presented here has greatly improved the adaptability of spline subdomain method and developed its applied range,for the nodes can be set arbitrarily in the longitudinal direction and each circumferential nodal line. |
