“…Analytical and numerical analysis of structures consisted of FGM coating layers has been recently studied [8][9][10][11][12][13]. In most of them, deformation of FGM coating on homogeneous substrate is investigated in the framework of the elasticity theory where the material composition is assumed to vary smoothly based on some mathematical models including linear, exponential and power functions.…”

Development of new coating systems has been an important issue over the years with the motivation\ud of extending the effective life of mechanical elements. For this intent, functionally graded materials have\ud been recently used in a variety of applications as promising replacements for conventional coatings. In the\ud present study, a hybrid coating system taking advantage of graded composition concept is proposed to enhance\ud the through-thickness stress distribution within a double-sided coated circular thick homogeneous plate. The\ud coating system is composed of two main layers: an external homogeneous layer and an interlayer between\ud the external layer and the plate, with graded material composition. All layers are modeled within the context\ud of three-dimensional elasticity theory, and an elasto-static solution is obtained by using suitable potential\ud functions.Accuracy and reliability of the proposed analysis is investigated by comparison with results obtained\ud in the literature, as well as with the results of a three-dimensional finite element simulation. Comparative study\ud shows the inherent advantages of the present hybrid coating system over the conventional homogeneous coating\ud or the functionally graded coating layers

An analysis of a coupled plane thermoelastic problem for a graded orthotropic coating-substrate structure is performed under thermomechanical loading conditions. The crack direction is parallel to the free surface. Applying the superposition principle and Fourier integral transform, the heat conduction and plane elasticity equations lends themselves to the derivation of two sets of Cauchy-type singular integral equations. The thermal stress intensity factors are defined and evaluated. In the numerical results, the effects of the orthotropy parameters, thermoelastic non-homogeneity parameters, and dimensionless thermal resistance on the temperature distribution and the thermal stress intensity factors (TSIFs) are studied. The obtained results can be used to design graded orthotropic coating-substrate structures under thermomechanical loading.

“…Based on the analyses of the above-mentioned investigations, there are many studies on the effects of the orthotropic and mechanical parameters on the SIF or on the ERR (Akbarov and Turan, 2009, Oneida et al, 2015, Ding and Li, 2014and Yusufoğlu and Turhan, 2012. However, these studies were discussed within the framework of the two-dimensional (2D) problem formulation.…”

In this study, a rectangular prism made of an orthotropic material is considered. It is assumed that this prism contains a band crack whose edge-planes are parallel to the upper and lower face planes. It is also assumed that uniformly distributed normal forces are imposed the top and bottom surface of the prism. The aim of this paper is to analyze the effect of the shear modulus on planes which is perpendicular to the crack's edge-planes and parallel to the crack's front on the Energy Release Rate (ERR) for different geometric parameters in a rectangular prism. The mathematical formulation of the corresponding boundary-value problem is carried out within the framework of the 3-dimensional linear theory of elasticity. In order to solve this problem, the 3D finite element method was employed. The numerical results are presented.
