Abstract

On the basis of the general theory of perforated thin plates with large deflections, the variational principles in terms of deflection w and stress function F are established. And from these principles the finite element method analysing the buckling and post-buckling of perforated thin plates is established. It can be seen that the porperty of element is more complex due to the multiple connectedness of the region.
