If the clutch can't transmit all that the engine can procduce, it will slip. Slipping under a high torque load and lots of RPMs makes lots of heat, which will overheat the friction surfaces of the clutch disk. The flywheel will absorb some of this heat, but the pressure plate is generally less massive and will get hotter and not absorb as much heat. You can see this sometimes in tht the pressure-plate side of the friction disk tends to wear more or get glazed more than the flywheel side. If the pressure plate gets too hot, it can fracture from the stress of uneven expansion.
oh i see what about dual mass flywheels, DMF do they fail because of the heat they absorb ? or is it shocks and vibrations like lugging, idling since there are more vibrations ?
