| Abstract: | The incremental governing differential equations of rectangular plates with geometric and materialnonlinearities as well as initial imperfections, which subjected to in-plane compression . are derived inthis paper, and are solved by Galerkin-collocation method. The numerical calculations show that theresults of this paper are in good agreement with those of theory and experiment obtained by other au-thors. |
