| Abstract: |
| Based on the theory of strip distributed transfer function method (SDTFM), a new element, called generalized super-element (GSE) is given for 2-D problems and its stiffness matrix and nodal force vector are derived. With the use of generalized super-element, the application of SDTFM is extended to the 2-D problems of arbitary geometrical boundary. |
