| Abstract: | In this paper, the asymptotic postbuckling theory is used for total initial postbuckling analysis of stiffened plate and shell structures.In the approximate Potential energy functional the small termsa reret ained as much as possible.lt is generally helpful for the precision of asymptotic solution (harmless at least). In addition, the error due to appropriate reduction of the calculative area is discussed.A smallfi nite element program is given.The numerical results show that the method and progra mare simple and convenient, in analysis of postbuckling behavior for stiffened plate and shell structures. |
