| Abstract: | In this paper,the postbuckling behavior of thin rectangular plates,with aspect ratio of 2,under simply-supported and damped boundary conditions,is experimentally studied and anlysed.The moire fringe method is used to showthe change of deflected shape of the whole plate after buckling,which compensa-tes the defects of previous experiments.The secondary buckling of simply-sup-ported plates is observed in the experiment. |
