| Abstract: | The postbuckling behavior of an annular plate under co-planar compression and lateral loads is studied. By use of the difference method, non-linear differential equations of large deflection and the boundary conditions with original disturbances have been directly solved. The buckling displacement of the annular plate and the boundary of stability are calculated. This method is simple and is easily handled in computer. The results obtained are in good agreement with Koiter's stability theory. |
