THE STATE OF STRESS-INDUCED BY CYLINDRICAL SLIDING CONTACTS WITH FRICTIONAL HEATING

Two elastic cylinders, which in general may be elastically dissimilar, are pressed together by a normal force and slid over one another. A frictional shear traction is developed which also generates heat along the interface. It is assumed that one body is an insulator and that the contact patch traverses the conducting body. In the paper we first solve the coupled thermo-elastic contact problem and then find explicitly the total state of stress in the conducting body. A quantitative assessment of the relative importance of thermal effects on the strength of the contact is then made. © 1990.
