| Abstract: | The finite dynamic element method(DEM) is quite efficient in improving the accuracy of the dynamic analysis of structures. In order to expand the application field of the DEM, based on the studies by Przemieniecki and Gupta et al, a two-dimensional quadrangular finite dynamic element is established in this paper, and its dynamic shape functions, stiffness and mass matrices developed herein can be used in practical analyses. |
