| Abstract: | In this paper, a finite element method of lines with the consideration of the geometric non-linearity of large displacement is established for the analysis of thin rectangular plates. In the theory, the corresponding matrix formulae have been derived and the difficult problem for the continuity of the deformation and the mutually restrained conditions at the conjunctions of plates have been considered properly. In the numerical examples, it is shown that the present theory by authors is reliable and accurate. |
