Abstract: In this paper, the modified iteration method is further generalized to the study of axisymmetrical postbuckling of thin circular plates and hereby a new approximate analytic solution of the problem is obtained. Further utilizations of this method to postbuckling analyses of plates of more complicated structure are expected.

Key words: thin circular plate, geometrical nonlinearity, postbuckling, modified iteration method
