A thermo-mechanical modelling of the Tribological Transformations of Surface

Abstract : 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.
