High number of researchers in the thermoelastic field assumed that the contact surfaces of the automotive clutches and brakes are flat, and they do not take the actual surface roughness into consideration in the numerical models. In this paper, a new model of rough clutch disc has achieved to show the actual contact pressure of the new and used friction facing of clutch disc. The effect of the surface roughness of the used friction facing on the heat generated and the temperature fields are investigated as well. The comparison has been made between the results when assuming the surface is rough and when it's flat. Axisymmetric finite element model has been developed to study the thermal behaviour of a single-disc clutch system (pressure plate, clutch disc and flywheel) during the sliding period.en1451-209220153241248https://creativecommons.org/licenses/by-nc-nd/3.0/ContactDry friction clutchFEMFrictional heatingTemperature fieldTechnikJournal Article10.15480/882.298710.5937/fmet1503241Ahttps://www.mas.bg.ac.rs/_media/istrazivanje/fme/vol43/3/11_oiabdullah.pdf10.15480/882.2987Journal Article
