| Abstract: | In this paper, the boundary ?integral equations and the boundary ?element method computing critical loads of perforated plates subjected to the external boundary forces in the mid ?plane are established based on the general mathematical theory for non ?linear analysis of perforated plates. As examples, the critical loads of annular plates under the uniform radial pressure and shear forces are given. |
