| Abstract: | The dynamic problem of the rectangular plate with fixed edges, for which there is not any accurate solution, is solved in this paper by combining the cubic B spline and weighted residuals. The method is compared with the finite differential method. It is evident that the spline collocation method is a more effective numerical method, the computation accuracy of which is high and the program of which is easy to edit. The calculation is timesaving. |
