I'm working on friction plate of clutch.

When the friction clutch begins to engage, slipping occurs for 3 sec period of time between the contact surfaces  such as pressure plate, clutch disc and flywheel and due to this slipping, heat energy will be generated in the interfaces friction surfaces. At high relative sliding velocity, high quantity of frictional heat is generated which lead to high temperature rise on the clutch disc surfaces and hence thermo‐mechanical problems such as thermal deformations and thermo‐elastic instability can occur. Hence high thermal stress & contact stresses can lead to thermal cracking . The high thermal stresses, generated between the contacting surfaces of clutch system such as pressure plate, clutch disc and flywheel due to the frictional heating during the slipping, are considered to be one of the main reasons of clutch failure for contact surfaces. In some cases temperature exceeds the maximum temperature limit of the material and eventually leads to premature failure. This is the main problem which occurs in Force-Travel vehicle clutch plate. Hence there is need to do thermo-mechanical analysis of clutch disc .

For calculating thermal stresses in Software i have to calculate heat generation due to frictional heating by numerical method.i have also design the whole clutch assembly.

After design,im confused about how to start for calculating heat generation due to friction by non linear numerical method?
