| Abstract: | An iteration method with multiple variable parameter correction is presented first. Then the large deflection problem of circular plate fixed on nonlinear elastic foundation and subjected to uniform load is investigated by using this method and an analytic solution of degree 2 with higher accuracy is obtained. Compared to the solution of the same problem but with linear elastic foundation, it is found that the solu- tion obtained has reasonable physical meaning and could be taken as a reference in engineering. |
