Inelastic buckling of rectangular plate

What is it about?

Thin rectangular plates are important structural elements used in various fields of engineering such as civil engineering, mechanical engineering and aerospace engineering. Thin-walled plate elements are often prone to buckling because of the action of high compressive forces, and sometimes inelastic buckling may occur. In this paper, we present a novel solution to the inelastic buckling problem of a thin rectangular isotropic plate with two clamped longitudinal edges and two simply supported edges (CSCS plate) using work principle and Taylor-Maclaurin series deflection function.

Why is it important?

Solution to the inelastic buckling of a thin rectangular CSCS plate using work principle and Taylor-Maclaurin series deflection function is presented for the first time. The results of our study compare favourably with the results from a previous investigation, with the maximum difference being less than 5 per cent. The method proposed in our study involves less computational effort and is applicable to a wider range of boundary conditions than trigonometric function approaches.
