New Challenges in Numerical Simulation of Forging Processes:
Multiscale and Multiphysics Approaches
FEM Forging Project ( more information )
Industry must demonstrate the ability to develop, process and join increasingly diverse and complex materials, in a well-controlled manner and in all economic sectors: aerospace, nuclear, defense, energy ... To meet these requirements, processes evolve and new appear. Another demand of the industry is to work across the entire range of manufacturing steps or life cycle of products: from the development of the material and its forming processes to recycling without forget the steps of heat treatment, assembly and usage properties. This serves two purposes:
- • better control of the material flow and energy and have a global vision of the transformation of materials,
- • But above all, take into account the effect of the inheritance of properties, structures, defects from upstream to downstream processes.
Multi-physics and multi-scale modeling is a key driver in such actions. We will give examples of numerical challenges that have missions to meet these industry needs. In metal forming industry, elimination of internal defects is a prerequisite to avoid catastrophic failure of part. Advanced numerical methods such as level set methods to describe the interface followed within a framework of finite element formulations can be used to model the germination, growth and void closure in the ductile damage. The same level set method can also be used to simulate grain growth and polycrystalline microstructures mobile interfaces. Finally, heat treatment like heating (including induction heating) and quenching are also of major importance in the workpiece life and must be simulated accurately by coupled modeling of several fields of physics: mechanics, heat, electromagnetism, chemistry, metallurgy.

Q & A Session
ClosingThis webinar is the second of two sponsored by the FEM Forging project, which is funded by the EU under the Leonardo initiative. The project is focussed on the development of continuous training of specialists on design and optimization of hot, warm and cold FORGING processes using FEM simulation technologies. Further information is available on the project website at FEM Forging.
Who Should Attend?
The target audience for this webinar are managers, engineers, analysts who wish to understand the capabilities and potential benefits of using FEA simulation in the Forging industry.
Professor Elisabeth Massoni
Elisabeth Massoni is the director of CEMEF (Materials Forming Center). CEMEF belongs to MINES ParisTech institution and is located in Sophia-Antipolis in the south of France. Research is multidisciplinary at CEMEF, from fundamental research to applications. Based on fundamental studies, the centre’s research activities are focused on physical and mechanical understanding of the principal aspects of materials processing and forming. Numerical codes on metal and polymer forming are then developed in the laboratory and industrialised by the software company Transvalor. The specificity of these codes is the different level of coupling: multi-scale, multi-materials and multi-physics. Around 160 people are working at CEMEF, about 60 permanent staff and 70 doctoral students.
The field of expertise of Elisabeth Massoni is on numerical simulation of metal forming processes (thin sheet forming, flow forming, hemming,..) and heat treatment. It concerns mainly the development of large strain behaviour, plastic anisotropy, nonlinear isotropic and kinematics models. These activities are mainly conducted through Phd research projects(around 25) in close collaboration with the industry in different economic sectors (automotive, aeronautics,…).
Elisabeth Massoni is also member of the board of CSMA(French Computational Structural Mechanics Association), ESAFORM (European Association of Material Forming), Pégase French Aeronautices cluster. She is also president of a SF2M (French Society on Metallurgy and Materials)Commission on Thin Sheet Metal Forming and Super plasticity.

CEMEF – Centre for Material Forming
Research Lab of the top-level French Engineering School, MINES ParisTech and associated with the French Research Foundation, CNRS, CEMEF – Centre for Material Forming processes – studies the materials from manufacturing down to their end-use properties for various industrial applications:
- Nuclear engineering,
- Automotive industry,
- Sustainable development,
Researches are carried out on a large range of materials: metals, synthetic and bio polymers, food stuff, composites and nanocomposites, glass, ceramics…
They aim at understanding materials behaviour at the different scales of their processing, the interaction with tools, the impact on their final properties.
Projects often mix experimental and numerical approaches.
Our aim is to develop an industrial research in direct connection with Industry and to educate students to research matters.
CEMEF is located in Sophia Antipolis, the first Technopark in Europe. It is situated on the French Riviera, 20km from Nice and Cannes.
