| Abstract: | A quasi-conforming nine-node quadrilateral finite element for multi-layered composite plates and shells is presented. This finite element is derived on the basis of the Hu-Washizu variational principle with independently assumed displacement fields, laminated interal strain fields and stress fields. Several problems of composite plates and shells are computed. The computed results show that the present element's performance is good in accuracy and efficiency. |
