• plane strain condition

Displacement potential formulation of orthotropic composite materials is extended for the plane strain condition. Different displacement and stress components and the governing equation are expressed as a single potential function for orthotropic composite materials. Using the developed single-function potential formulation, a one-end fixed, thick, stiffened T 300/5208 carbon epoxy plate subjected to uniform tension at its right lateral end is solved as an example to show the applicability of the present approach. Different displacement and stress components at different sections of the plate are discussed with the help of graphical solutions. The solutions of the same problem mentioned in the article considering boron/epoxy plate under plane stress condition obtained by the present analytical approach is compared with those of finite difference and finite element method to verify the validity of the present results.
