Analytical and Numerical Solutions for the Thermal Problem in a Friction Clutch System

The dry friction clutch is an important part in vehicles, which has more than one function, but the most important function is to connect and disconnect the engine (driving part) with driven parts. This work presents a developed numerical solution applying a finite element technique in order to obta...
