“…Other than that, the temperature rise in the contact area can also be calculated either by the analytical method [13][14][15][16][17] or by the numerical method [18][19][20][21][22][23].…”

“…Spiryagin et al [22] recommended a mathematical model to calculate the temperature in the wheel-rail flange contact to detect the lubricant type at this contact location. Numerical algorithm was applied by Chudzikiewicz et al [21] to build up a thermoelastic model with elastic graded materials to investigate the frictional heat generation and heat transfer across the contact surface. Another 2D FE model built up by Wu et al [20] was utilized to investigate the residual deformation, plastic strain and residual stress at the rail surface during wheel-rail sliding contact.…”

“…Using (76) as well as (86) we obtain that, as ρ → 0 + , This problem is described by the quasistatic elliptic variational inequality (Chudzikiewicz and Myśliński, 2009). The topology optimization approach is useful in reducing the normal contact stress, which is the main factor generating rolling contact fatigue and noise during the movement of the body in contact with the foundation.…”

This paper deals with the formulation of a necessary optimality condition for a topology optimization problem for an elastic contact problem with Tresca friction. In the paper a quasistatic contact model is considered, rather than a stationary one used in the literature. The functional approximating the normal contact stress is chosen as the shape functional. The aim of the topology optimization problem considered is to find the optimal material distribution inside a design domain occupied by the body in unilateral contact with the rigid foundation to obtain the optimally shaped domain for which the normal contact stress along the contact boundary is minimized. The volume of the body is assumed to be bounded. Using the material derivative and asymptotic expansion methods as well as the results concerning the differentiability of solutions to quasistatic variational inequalities, the topological derivative of the shape functional is calculated and a necessary optimality condition is formulated.

“…However, the stresses of the contact may lead to plastic deformation. Several researchers studied the problem of the mechanical contact between two bodies in the elastic phase [23][24][25][26][27][28]. Due to the nonlinearity of the material behavior with plastic deformations, the experimental methods and the numerical calculations are used to determine the material deformation.…”

“…At high temperature applications, the heat transfer due to temperature variation has a significant effect on the material properties [37][38]. Thermomechanical contact was studied with elastical behavior [24,39]. Authors have analyzed the effects of high temperature and high pressure on stressstrain distribution.…”

This study presents the development of a thermo-mechanical simulation model for an elastic-plastic contact problem between a half cylinder and a plane plate. The set of equations was solved using direct coupling method by Ansys mechanical. The results obtained from the present numerical model of the structural contact without heat transfer are compared with those of analytical, experimental and other numerical models. Then, the contact problem was solved using a coupled thermo-mechanical model. Computational results showed significant effects of thermal consideration in the elastic-plastic contact problem. Large deformations of structure due to high temperature are predicted using the thermo-mechanical model with elastic-plastic deformations. This model is useful to predict deformations on the structural components due to contact at high temperature situation.
