ABSTRACT
This article presents the failure analysis of a clutch disc in a two-ton truck. The failure part was made of high-carbon steel for springs. Although the failure surface was very thin and difficult to interpret, the fracture surface examination revealed chevron marks and the presence of faint beach marks. The failure parts were made of hardened 1070 carbon steel. The cushioning plate experienced shear and bending alternating stress. The end failure is caused by shock load.
