VIBRATION ANALYSIS OF LAMINATED COMPOSITE PLATES USING SUPER ELEMENTS

For analysis of structures, the finite element method has been widely used among the avalable approximation methods. However, in the conventional finite element method, many elements are required for obtaining accurate results, hence, the amount of time and relation costs are usually considerable. An advanced technique, which has recently been widely implemented, is the application of super element in the preliminary design of structures. In this paper, a sizeable composite plate can be considered as one single super element, reducing analysis and assembling time drastically. Results of this study indicate that there is a good agreement between single super element and other methods.
