| Abstract: | The free vibration of moderate thick plate was analyzed by generalized conforming element and Coons surface approach for thick and thin plates in the literature~([1]).The generalized conforming element has many advantages such as less degree of freedom,high precision,easy to be programmed and rapid convergence.In addition,examples in this paper give the roots of the frequency of rectangular plate supported along four sides,the results are approaching to those of reference [2]. |
