Abstract
The objective of this study is to investigate the thermomechanical cracking problem between the friction surface and the interior of the vehicle brake disc. Analytical model was considered for a semi-infinite solid subjected to the thermal loading of an asperity moving with a high speed. The temperature field and the thermal stress state were obtained. Analytical result showed that the dominant stress cracking of friction brake is thermal stress and cracking location is dependent on the friction coefficient of contact and the Peclet number. Friction and Peclet number influence the thermomechanical cracking of friction brake disc. On the basis of analytical results, thermomechanical cracking model was proposed.
