Abstract: In this paper, the buckling problem of non-uniform columns subjected to axial concentrated and distributed loading is studied. The expression for describing the distribution of flexural stiffness of a non-uniform column is arbitrary, and the distribution of axial forces acting on the column is expressed as a functional relation with the distribution of flexural stiffness and vice versa. The governing equation for buckling of a non-uniform column with arbitrary distribution of flexural stiffness or axial forces is reduced to a second-order differential equation without the first-order derivative by means of functional transformations. Then, this kind of differential equation is reduced to Bessel equations and other solvable equations for 12 cases, several of which are important in engineering practice. The exact solutions that represent a class of exact functional solutions for the buckling problem of non-uniform columns subjected to axial concentrated and distributed loading are obtained. In order to illustrate the proposed method, a numerical example is given in the last part of this paper.

TL;DR: In this paper, the bending behavior of wheat and barley stalks is similar to that of steel tubes and two consecutive phases can be distinguished: ovalisation and buckling, and the presence of a core-rind structure increases the bending resistance of the stems.

TL;DR: Finite element technique extended for plastic buckling of flat plates, using Stowell theory as mentioned in this paper, has been used for flat plate buckling in the last few decades, and has been shown to work well on flat plates.
