In this paper, the fully-coupled rolling contact problem between a rigid cylinder and an orthotropic medium is investigated. The governing equations are developed analytically; then, a numerical method, the Gauss-Chebyshev method, is used to solve the coupled integral equations. The rolling contact problem is solved by assuming a central stick zone accompanied with two slip regions. The main purpose of this study is to obtain the surface stresses in the contact area and investigate the effect of material orthotropic properties such as shear parameter and stiffness ratio and also the coefficient of friction on these contact stresses. In addition, the subsurface stresses in the orthotropic medium are determined and a parametric study, was subsequently executed. The current paper shows that the orthotropic parameters and the coefficient of friction significantly influence the contact surface stresses and the distribution of the interior field stresses. By appropriately choosing the values of these parameters, the stresses will decrease; thus, the failure behavior of the orthotropic medium improves.

Abstract. The evaluation of interface mechanics was very useful for the design of thin solid film. According to the method of image, interface stresses and deformations of coating-substrate system were gained. Using this mathematical calculation model, the indentation test data was carried out and the results were analysed. Based on the mechanical model and test, the critical state of interface stresses from elastic deformation to plastic yield was evaluated. From experimental and calculating results, interface shear stress and normal stress had different affecting level for the coating failure under the same surface load. And a fitting relationship equation for the two stresses was also gained to determining the failure value in designing. The method of this paper could be used for thin film interface mechanics design and evaluation.

“…Rolling of a coated material was investigated by Usov and Danilov (2007) by deriving the exact solution in case of an elastic coating and a rigid substrate material. A functionally graded elastic coating was recently studied by Guler and coworkers (Alinia et al, 2014;Guler et al, 2013). While these studies provide valuable insight into the mechanical behavior of a polymer during rolling, the behavior of a non-linear visco-elasto-plastic polymer coating on a steel substrate and the evolution of its thermodynamic state during rolling has not yet been investigated.…”

a b s t r a c tA novel methodology is presented for pre-conditioning a polymer-coated steel used in food and beverage packaging. Mechanical rejuvenation of the coating via rolling is studied in order to prevent interface damage in subsequent forming operations. The simulations reveal that the thermodynamic state of the polymer coating after rolling depends on the rolling reduction. This dependency can be used to tailor the thermodynamic state of the coating prior to can production. A proof-of-principle simulation was performed to study the effects of rejuvenation on subsequent deformation processes. Deformation-induced interface roughening was studied for the initial and rejuvenated polymer coating. The predictions for a rejuvenated polymer coating indicate a significant decrease in interface damage.The presented numerical framework allows for a detailed study of the effects of pre-conditioning on the interface integrity during subsequent forming operations. With properly identified material parameters, it becomes possible to tailor the polymer-steel material properties before and during production to minimize interface damage during production and storage of cans or canisters, e.g. for food and beverage packaging.
