Crazing and uni-directional cracking of the braking surfaces of ventilated disc brakes has been an interminable problem for the brake designer. Craze cracking is associated with material structure changes due to excessively high surface temperatures. These conditions do not lend themselves to simulation and can generally be avoided by correct sizing of the brake components. This paper details a method using non-linear Finite Element based techniques to simulate the conditions leading to uni-directional cracking of the braking surfaces and proposes a ventilated disc brake design to combat this problem.
