description: This diploma work is devoted research of influence of microparameters on wear of a material. In work various problems connected with contact of firm bodies, namely a normal problem of Hertz, a tangential problem of Hertz, the combined problem of Hertz and a thermomechanical combined problem of Hertz have been considered. Analytical and numerical solutions were found for the normal Hertz problem. The tangential Hertz problem was considered separately but it was found to be of no practical value. The combined Hertz problem was solved numerically for certain material constants and given loads. Results were obtained which could be used for material wear analysis. The thermo-mechanical combined Hertz problem was examined in terms of temperature. It was found that the stresses increased by a factor of nearly 2 in comparison to the normal Hertz contact problem without temperature. From this it can be concluded that heat dissipation plays a decisive role in wear resistance. The dependence of the various parameters on wear has also been examined and correlates with real experiments. Thus, this thesis is actual research aimed at study of material wear processes in conditions of solid body contact using numerical methods.
