Abstract:

In this research, local elastic buckling of the plates is studied with different boundary conditions under periodic and uniform compressive loadings by analytical direct method (Equivalency in Partial Differential Equation: EPDE) and FEM modeling in rectangular plates. Also, new formulations are presented for determination of critical buckling loads under uniform loading in rectangular plates. In this study, governing differential equation is used for thin plates under lateral and direct periodic and loadings. Next, the mentioned equation would be solved by assumed displacements by direct smart method. Therefore, the minimum critical buckling load is obtained for first mode of buckling by theoretical and finite element methods. These analytical results are validated by the FEM modeling. Finally, good agreements are found between the analytical and numerical predictions for the critical buckling loads.
