Physico-mathematical modeling and informational technologies| Zusammenfassung: | The partial frictional slip of two semi-infinite bodies of similar materials in the presence of amedium in an intercontact gap has been investigated. The cause of microslip is thermal strainsinduced by heat flow. Both mechanical influence (pressure on the surfaces of the bodies) andthermal influence (thermal resistance) of the gap filler have been taken into account. As amathematical model of the interstitial medium, the ideal gas has been chosen. The formulatedcontact problem has been reduced to two singular integral equations for a gap height and arelative shift of the surfaces of the bodies and a Prandtl singular integro-differential equation fora temperature jump between the gap surfaces. Numerical calculations have been carried out whenthe material of the bodies is stainless steel AISI 304 in the presence of air or carbon dioxide in thegap. The effect of the medium pressure and applied load on the width of the slip zones and therelative shift of the surfaces of the bodies has been analyzed. |
