摘要
本文对长宽比β=2的受压矩形板在简支、固支边界条件下的初始屈曲和后屈曲性态作了系统的试验研究和分析.试验中应用了光栅云纹法,显示整个板的挠曲位移场,在初始屈曲和后屈曲过程中的波形变化,并观察到了简支板的二次屈曲现象.
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.
