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.
Key words: Analytical and numerical methods , buckling of plates, EPDE, periodic and uniform loadings, rectangular, ,
