Study of Plate Buckling due to Various In-Plane Loads Combination

Abstract

The present thesis introduces a new procedure to obtain the critical buckling loads in several cases of flat rectangular plates with different boundary conditions and loading forms. This procedure has the advantage of simplicity and easiness to use compared to the relevant methods found in literature. Moreover, it has been proven that the proposed procedure gives both good results and acceptable accuracy. Models of Ansys-14.5 ® have been used for certificating the results.

The present work offers also a procedure of getting the critical buckling loads in the case of non-rectangular shapes of flat plates such as trapezoidal, hexagonal, elliptical, and even any form of irregular shapes. Finally, our proposed method has been successfully used to get the critical buckling loads in some applications in mechanical and civil engineering such as cams and corrugated webs.
