| Abstract: | In this paper, a new analytic solution of large amplitude fundamental vibration of circular and annular thin plate with multistepped thickness is given, by means of modify iteration method, and an analytic relation for the amplitude frequency response is derived. The perfect results are also given for the engineering practice. |
