For the solution of the buckling of plates with the discontinuous boundary conditions, the energy methods have been the most powerful and usefulfor engineering purposes. The recent development in high speed digital computers has been giving favor to a numerical approach, termed "the finite element method". The authors developed the finite element method for the elastic, elastic-plastic and plastic buckling of plate and obtained quite satisfactory results for the case of uniform compression. In the paper, the authors applied the method to the buckling of plate with highly complicated boundary conditions. As a basic example of the application, the compressive buckling of the plate with discontinuous boundary conditions was solved by the method and compared with the analytical solution obtained by the energy method. The result was quite satisfactory and suggested the usefulness of the method.
