Initial sizeof the uniform load has little influence on thegeneral temperature which may alter theproperties of the materials. Role of slip velocityis also small.In case the material has different propertiesfrom the point of view of transfer of heatproduced by friction will be taken from the heatconductingbody and the limit between stabilityand instability depends on the relative slidingvelocity.REFERENCES[1] DOW, T.A; BURTON, R.A. “Initiation ofthermo elastic instabilities of slidingcontact in the absence of wear”, Wear, 19(1972)[2] DOW, T.A; BURTON, R.A. “The role of wearin the initiation of thermo elasticinstabilities in sliding contact”, J.
