摘要：

This paper deals with the wrinkling and buckling of elastic plates subjected to in-plane and transverse external forces. With the aid of a newly developed dynamic relaxation method, the well-known dynamic criterion of stability was used to predict the bifurcation point. Some typical components in engineering practice (i.e. annular, circular and rectangular plates) were investigated in detail. The reliability of the method for the analyses of post-wrinkling and post-buckling was demonstrated. Based on the analytical studies performed, approximate formulas for determining the critical load and number of waves in the wrinkling mode were obtained. It found that the initial elastic wrinkling mode of plates subjected to bending was different from that of plastic wrinkling. (C) 1997 Elsevier Science Ltd.
