The Tribological Transformations of Surface (TTS) are observed on samples of certain steels undergoing repeated compressive loadings. They correspond to a permanent, solid-solid phase transformation localized on the surfaces of the sample on which the loading is applied. The main hypothesis of the study is that TTS are not only due to the mechanical loading but also to the thermal loading which is associated to. Thus, a thermo-mechanical model is first proposed in the present paper, which is inspired by previous works on TRansformation Induced Plasticity (TRIP). The potentialities of the model are also briey illustrated by a simple 1D example. Les Transformations Tribologiques de Surface (TTS) sont observées sur des échantillons de certains aciers soumis à des chargements compressifs répétés. Elles correspondent à des changements de phase solide-solide irréversibles localisés sur les surfaces mécaniquement sollicitées des échantillons. L'hypothèse centrale de cette étude est que les TTS ne sont pas dus au seul chargement mécanique mais également au chargement thermique qui l'accompagne. Un modèle thermo-mécanique est ainsi proposé, qui s'inspire de travaux antérieurs sur la plasticité de transformation (TRIP). Un exemple (1D) illustratif des potentialités de ce modèle est également présenté. |
