A mean to better understand the complex phenomena involved in the cutting process is to better qualify the behaviour law used in the simulation of machining processes (analytical and finite element modelling).The aim of this paper is to present the choices made regarding the behaviour law. Our study is based on a strain-gradient plasticity theory with at first a brief state-of-the-art review, we then concentrated our efforts on the strength and limitations of such theories in the context of machining. Gurtin's work on strain gradient plasticity shows the most promising insight toward our work. We finally present what our initiatives, regarding this existing work, will be in order to present a road-map for our future work.< Réduire
