Investigation of the effect of orthotropic parameters in failure of orthotropic materials under the rolling contact

In this study the effect of orthotropic parameters on failure of the orthotropic materials under the ‎rolling contact problem is investigated. Rolling contact problem between a rigid cylinder and an ‎orthotropic half space for the specific regime of contact zone, a central stick zone accompanied ‎with two slip zones, is considered in plane strain condition regarding the Coulomb law of friction. ‎ Although the problem is analyzed using the previous methods obtained in our last paper, in this ‎paper the main emphasis is on the results and the dependence of the surface and subsurface ‎stresses on the orthotropic parameters and the coefficient of friction. ‎ The interesting results from this study suggest that the‏ ‏stresses can be reduced by controlling of ‎the orthotropic parameters and, as a result, increasing the life of the orthotropic media. Finally, it ‎can be concluded that the replacement of orthotropic and non-homogeneous materials instead of ‎isotropic and homogeneous materials will be caused in many applications to increase the life of ‎the components and reduce the cost of consumables.‎‏ ‏
