Experimental and numerical analysis of thermal striping in automotive brake discs

Résumé

In the present study, thermal striping development on friction bands of brake discs is investigated through an experimental and numerical analysis. A test consisting of a series of several hundred severe brakings was carried out on a specific bench at PSA Peugeot Citroën. The experimental observations of the crack network evolution and a numerical analysis of a brake disc with a single crack helped to propose a macroscopic criterion capable of predicting the criticality of the network, namely, its ability to lead to the complete failure of the structure. In addition, a numerical analysis of the crack shielding process is developed whose results are compared with experimental findings.
