“…Sliding contact analysis of a finite thickness orthotropic graded coating was employed [69]. Three-dimensional solutions were obtained for transversely isotropic coated structure under circular flat punch contact, in which the optimal thickness of the coating has been studied [70]. Evidently, these analyses will contribute to the delicate design of the coated structure.…”

This article reviews fretting wear damage in industries and in the contact mechanics of coated systems. Micro-slip motion resulting in fretting damage is discussed along with major experimental factors. The experimental factors, including normal force, relative displacement, frequency and medium influence are directly compared. Industrial solutions to reduce fretting damages are then discussed. The contact mechanics of a coated system are reviewed to quantify stress states in a coating layer and the substrate. Finally, a literature review on simulation for fretting is carried out. This review study provides useful methods and practical solutions to minimize fretting wear damage.

“…Indentation problem of transversely isotropic material with functionally graded coating was considered by Vasiliev et al [21], using Hankel's integral transformation. By the Green's function method, Hou et al [22] also derived three-dimensional analytical solutions to smooth and frictional contact problems of transversely isotropic coated material. Argatov [23] compared general solutions of contact pressure in literatures for non-axisymmetric circular contact problems.…”

The novelty of this paper is to propose exact three-dimensional analytical solutions to the half infinite thermo-elastic body pressed by a rigid cylindrical structure for the first time, in which uniform heat flux flowing from rigid structure into the half infinite body is considered. Using recent general solutions expressed by four harmonic functions and extending potential theory method to consider heat effect, the governing integral equations are first derived. Then, the equations are analytically solved and displacement, stress, and temperature field components expressed by elementary functions are obtained. To validate the presented solutions, the correctness of the solutions is exactly examined, and normal contact displacement and stress without heat effect are compared with those in literatures. Furthermore, a numerical example which is the stainless steel thermo-elastic body pressed by a displacement restrictor is studied. Displacement, stress, and temperature distributions are analyzed, and the influence of heat flux on the pressed depth is also discussed in detail. The analytical solutions presented in this paper are rather important in engineering practice and can provide a basis for indentation analysis, displacement restrictor design, foundation settlement calculation, and so on.

“…Vasiliev [ 22 ] investigated the indentation of an electroelastic piezoelectric FG semi-infinite substrate by a rigid indenter under applied force and electric charge. Hou et al [ 23 ] analytically investigated the stress gradient in the coated structure under tilted circular flat punch by using 3D elasticity theory. Asiri et al [ 24 ] developed a predictive model to study the elastoplastic response during loading and unloading of nanocomposite structures indented by spherical punch.…”

Due to the applicability of new advanced functionally graded materials (FGMs) in numerous tribological systems, this manuscript aims to present computational and empirical indentation models to investigate the elastoplastic response of FG substrate under an indention process with spherical rigid punch. The spatial variation of the ceramic volume fraction through the specimen thickness is portrayed using the power law and sigmoid functions. The effective properties of two-constituent FGM are evaluated by employing a modified Tamura–Tomota–Ozawa (TTO) model. Bilinear hardening behavior is considered in the analysis. The finite element procedure is developed to predict the contact pressure, horizontal displacement, vertical deformation, and permanent deformation of FG structure under the rigid cylindrical indentation. The empirical forms for permanent deformation were evaluated and assigned. Model validation with experimental works was considered. The convergence of the mesh and solution procedure was checked. Numerical studies were performed to illustrate the influence of gradation function, gradation index, and indentation parameters on the contact pressure, von Mises stresses, horizontal/vertical displacements, and permanent plastic deformation. The present model can help engineers and designers in the selection of an optimum gradation function and gradation index based on their applications.
