Strain Gradient Plasticity Applied to Material Cutting

Abstract:

To better understand the complex phenomena involved in the cutting process is to better qualify the behaviour law used in the simulatiotrn of machining processes (analytical and finite element modeling). The aim of this paper is to present the choices made regarding the behaviour law in this context, indeed, commonly used behaviour laws such as Jonhson-Cook can bring unsatisfactory results especially for high strain and large deformation processes. This study develops a large deformation strain-gradient theoretical framework with hypothesis linked with to metal cutting processes. The emphasis of the theory is placed on the existence of high shear phenomena creating a texture in the primary shear band. To account for the texture, the plastic spin is supposed to be relevant in this theory. It is shown that the theory as the capability of interpreting the complex phenomena found in machining and more particularly in high speed machining.
