When normal stresses due to bending and/or direct axial forces are large, each plate (for example, flange or web plate) may buckle locally in a plane perpendicular to its plane. In order to prevent this undesirable phenomenon, the width-to-thickness ratios of the thin flange and the web plates are limited by the code.
By “thin,” it is meant that the plate’s transverse dimension, or thickness, is small compared to the length and width dimensions. A mathematical expression of this idea is: where t represents the plate’s thickness, and l represents a representative length or width dimension.

The thickness optimization is used to maximize the stiffness or the buckling load of a kirchhoff plate having constant volume. The shape of the plate is arbitrary and it is subjected to any type of admissible boundary conditions.
