| Abstract: | In this paper, to solve the buckling problem of lamiated composite material plates, by using Ritz method is discussed. We select Polynomial as the flexural function and obtain an analytical formula for calculating the critical load. Computed example shows that the result obtained by the author is near that in Ref1]. This paper yet points out that there may takes place the case that the rate collocation method is not applicable. |
