“…This outcome is consistent with previous research. 30,31 The comparison to the frictionless case demonstrates that friction does not significantly impact the contact traction when a slight indentation is reassured to maintain a small deformation on the elastic foundation.…”

SummaryThe contribution at hand aims at a numerical method to represent contact between two or more different solid bodies. The proposed computational contact algorithm is based on a displacement‐driven approach to describe the geometrical constraint resulting from the impenetrability of the solid bodies in contact. A solution method of contact between one deformable and one rigid body is assumed for the initial computationally fast implementation of the underlying equations. Elastic or inelastic material behavior can be considered for the deformable body. Furthermore, the proposed approach is capable of finite deformations. Moreover, a node‐to‐segment (NTS) formulation is utilized for contact element discretization. Various numerical examples are presented to demonstrate the numerical method's applicability for different contact mechanics tasks. First, the presented examples verify the displacement‐driven approach by investigating its convergence behavior and consistency. Then, comparisons of solutions by the proposed formulation to the analytical solution and the penalty method are provided to validate its accuracy. Moreover, the stick and slip condition of large sliding motion in a frictional contact problem is successfully depicted.

The contact problem for thermoelectric materials with functionally graded properties is considered. The material properties, such as the electric conductivity, the thermal conductivity, the shear modulus, and the thermal expansion coefficient, vary in an exponential function. Using the Fourier transform technique, the electro-thermoelastic problems are transformed into three sets of singular integral equations which are solved numerically in terms of the unknown normal electric current density, the normal energy flux, and the contact pressure. Meanwhile, the complex homogeneous solutions of the displacement fields caused by the gradient parameters are simplified with the help of Euler’s formula. After addressing the non-linearity excited by thermoelectric effects, the particular solutions of the displacement fields can be assessed. The effects of various combinations of material gradient parameters and thermoelectric loads on the contact behaviors of thermoelectric materials are presented. The results give a deep insight into the contact damage mechanism of functionally graded thermoelectric materials (FGTEMs).

This paper presents a multi-layer model for moving contact problems of functionally graded coatings whose physical properties have general spatial variations. The coating is assumed to be composed of an arbitrary number of layers and perfectly bonded to an elastic substrate. Wave equations for the layers and the substrate are derived in accordance with the plane theory of elastodynamics. The equations are solved by the application of Galilean and Fourier transformations. Flat and triangular punch profiles are considered, and the formulation is reduced to a singular integral equation of the second kind in both cases. The integral equations are solved by means of Jacobi expansion and collocation techniques. Proposed procedures are verified through comparisons to the results available for a special case in the literature. Parametric analyses are carried out for functionally graded coatings possessing ceramic-rich, metal-rich, and linear profiles. The results presented demonstrate the influences of factors such as punch speed, coefficient of friction, material property variation profile, and contact-length-to-thickness ratio on contact stresses, punch stress intensity factors, and required contact force. It is shown that the multi-layer model is required to account for general property distributions in a functionally graded coating subject to moving contact.
