This paper aims at developing an approach for thermo-mechanical fatigue design of automotive brake discs made of lamellar graphite (grey) cast-iron. The first step consists of modelling the nonlinear cyclic behavior and tension/compression strong dissymmetry of grey cast iron. The proposed model is based on the introduction of a second-order induced damage tensor. From the analysis of the damage mechanisms, a fatigue criterion based on the dissipated energy per cycle is proposed.
