“…The warping gets stronger for high temperatures and is less significant for S12155 geometry. This effect might be caused by secondary effects of short beams already observed by Hardy [24] when studied static analysis of short beams with homogeneous cross section. As the ratio between span and thickness of the cross section increases the distribution becomes less distorted.…”

A sandwich system of two steel faces and a polyurethane core is studied as a renovation system for orthotropic steel bridge decks. An experimental program has been carried out aiming to better understand the sandwich beam flexural behavior. The temperature significantly affects the sandwich flexural behavior. Increase in the temperature decreases the sandwich stiffness and strength. The stiffness is more difficult to predict at high temperatures due to the viscoelastic behavior of the core. Stiffer and stronger renovation solutions can be achieved by putting the extra weight on the core thickness rather than on the faces thickness. Stresses on the deck plate can be reduced by 60-95% using this renovation system.

“…But, somehow, the subject is still suffering from a lot of shortcomings and thus it is constantly coming up in the literature [1][2][3][4][5][6][7][8][9][10]. Many practical problems can be solved considering by the plane strain condition instead of three dimensional concepts.…”

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 paper 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.

“…Although the stress analysis has now become a classical subject in the field of solid mechanics, somehow these stress analysis problems are still suffering from many shortcomings and thus are being constantly looked into [46][47][48][49][50][51]. Elasticity problems are usually formulated either in terms of deformation parameters or stress parameters.…”

The present paper describes the advancement of displacement potential approach in relation to solution of plane problems of structural mechanics with mixed mode of boundary conditions. Both the conditions of the plane stress and the plane strain are considered for analyzing the displacement and stress fields of the structural problem. Using the finite difference technique based on the present displacement potential approach for the case of the plane stress and the plane strain conditions, firstly an elastic cantilever beam subjected to a pure shear at its tip is solved and these two solutions (plane stress and plane strain) are compared with Timoshenko and Goodier cantilever beam bending solutions (Theory of elasticity, 2nd edn. McGraw-Hill, New York, 1951); secondly the above-mentioned displacement potential approach for the case of the plane stress and the plane strain conditions are applied to solve a one-end fixed square plate subjected to a combined loading at its tip. Effects of plane stress and plane strain on the elastic field of the plate are discussed in a comparative fashion. Limitations of Timoshenko and Goodier cantilever beam bending solutions (Theory of elasticity, 2nd edn. McGraw-Hill, New York, 1951) over the displacement potential approach for the case of the plane stress and the plane strain conditions are not only discussed but also the superiority of the present displacement potential approach for the case of the plane stress and the plane strain conditions are reflected in the present research work.
