Abstract

This manuscript deals with the static and dynamic buckling of plates with non-rectangular shapes. The plate has an uneven imperfection and is made of natural composite materials. The model is validated with the existing results. The static buckling loads and the first natural period of the plate are first evaluated. Then, the imperfections are incorporated in the form of the first five buckling mode shapes, and the plate is subjected to in-plane loads. The effect of imperfection and inclination of the edges on the behaviour is evaluated. It is observed that due to the difference in the first five buckling mode shapes of the plates, the plates do not show any definite trend in both nonlinear static loading and nonlinear dynamic loading cases.
