Multi-physics / multi-scale analysis and numerical modeling of aeronautical metal alloys machining

Job Details

The project:

This project focuses on the multi-physics and multi-scale modeling on machining of metallic materials with different crystallographic structures. The important challenge of the proposed numerical modeling project is to understand how the cutting conditions affect the local formation of the shear band and especially to predict the microstructure on the material surface. To analyze the machining of metallic materials, it is necessary to adopt a proper computation approach, allowing access to the physical parameters of the cut. Physical modeling of material behavior plays a key role in the proposed approach. It is well known that the analytical methods has some limits, because it does not make it possible to include the complex thermomechanical behavior of the machined material and reliable tool / work  contact interfaces laws. Numerical modeling, often using the finite element method, makes it possible to introduce complex thermos-mechanical behaviors, and thus to predict physical variables difficult to be obtained by experimental means. The used constitutive material behavior model must reproduce the sensitivity to high plastic deformation, deformation rate and temperature together with damage estimation. For the considered metallic materials, it is also necessary to have modeling of their microstructure evolution induced by the cut and the local gradients of the thermomechanical variables. Specific strategy based on multi-scale and multi-physics modelling must be adopted to obtain plastic deformation / damage coupling, plastic deformation / microstructure coupling or the three together.

Futher Information:

This Fellowship is cofunded by Université Bretagne Loire and Région Bretagne

The Université Bretagne Loire federates 7 universities, 15 “grandes écoles” and 5 research organizations in the West of France (Bretagne and Pays de la Loire). This community of universities and institutions aims to develop the scientific and academic potential of this territory at national and international level.

The combined effort of the Region and other Breton communities is positioning Brittany today among the most active French regions in research and innovation. To facilitate the emergence of a knowledge-based economy, it has chosen to strengthen research and higher education upstream and to create an environment conducive to downstream innovation: a voluntary policy to encourage the creation of news in Brittany and to develop scientific research through financial support programs
