Buckling And Postbuckling Of An Imperfect Plate Subjected To The Shear Load

The stability analysis of an imperfect plate subjected to the shear load is presented. To solve this problem, a specialized computer program based on FEM has been created. The nonlinear finite element method equations are derived from the variational principle of minimum of total potential energy. T...
