Missions

this research project is part of a European project named “ModEL-FuturE” and is part of the European program M-Era.Net (https://m-era.net/), funded by national agencies.
Summary of ModEL-FuturE: The core innovation objectives of ModEl-FuturE are the creation of novel numerical tools for predictive wear simulations in combination with the elaboration of advanced experimental methods and the development of sustainable soft materials. Specifically, the numerical approaches address a so-called Digital Shadow for tire wear simulations considering damage, healing and abrasion features of a new generation of elastomeric materials. The Digital Shadow is a milestone on the roadmap to create a cyber-physical system. The innovative potential of the project fosters strongly the goals of sustainable development, such as a low carbon footprint of product processing and application, which is in line with the topical program. ModEl-FuturE has the potential for significant scientific and commercial impact, for all involved partners, through the generation of valuable intellectual property (IP) guided by a clear plan for the exploitation and dissemination of project results.
Academic partners involved :
• Leibniz-Institut für Polymerforschung Dresden e.V. (IPF), team leader : Prof. Dr.-Ing. Sven Wießner.
• Univerzita Tomáše Bati ve Zlíně (TBU), team leader : Doc. Dr.-Ing. Radek Stoček
• Technische Universität Dresden (TUD), team leader : Prof. Dr.-Ing. habil. Michael Kaliske
• Laboratoire de Mécanique et d'Acoustique (LMA), team leader : PhD habil. Stéphane Lejeunes

Activities

- Contribute to the developpement of a new material model adapted to represent the thermomechanical behavior of different technical elastomers (some of which will include non-covalent bonds and self-healing properties). The most ambitious and innovative part of the model is to include volumic damage and healing phenomena that can occur concurrently depending on the loading conditions (thermal and mechanical). This material model will be based on previously developped approaches at LMA and should include finite-strain, nonlinear viscoelasticity, thermomechanical couplings, damage and healing phenomena.
- Propose an elemental implementation of the developed model that will serve as a basis for the simulations that will be performed by TUD (Tecnische Universität Dresden)
- Propose a procedure for identifying material parameters using the tests carried out by IPF (Leibniz Institut für Polymerforschung) and TBU (Univerzita Tomase Bati)
- Participate in meetings and in the consortium's scientific dissemination strategy

Skills

A good knowledge of :
- Continuum mechanics
- behavior law
- Mechanics of polymers
- Finite strains,
- Chemestry of polymers,
- Finite elements
- Proficiency in English (read, write and speak)

Work Context

The Mechanics and Acoustics Laboratory (LMA) is a mixed research unit of the CNRS (UMR 7031) whose supervisory bodies are Aix-Marseille University (AMU), CNRS and Centrale Marseille (ECM).
The LMA has a staff of about 110 people, including 70 permanent staff (researchers, teacher-researchers, engineers, assistant engineers and technicians) and about 30 doctoral students.
The laboratory develops original research that ranges from the understanding of phenomena to the development of systems with high technological or societal implications, including their design or the development of basic concepts and technologies.
The LMA has nationally and internationally recognized expertise in the fields of Solid Mechanics and Acoustics.
It is structured into three research teams: Waves and Imagery, Sounds.and Materials and Structures.

Constraints and risks

The candidate will be expected to participate in various consortium meetings and possibly work at a partner's site for a short period of time.
