Post-Doctoral position offer - Thermomechanical modeling of volumic damage and healing in (self-healing) elastomers

Amphithéâtre François Canac, LMA

Le 12 mai 2022

Context : 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. The total project duration is 36 month.

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

Job description :

The candidate is expected to 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. A finite element implementation will also be carried out to perform simulations on tire structures. The model will be based on experimental observations to be performed by IPF and TBU and the material model will be integrated in a more global finite element model of wear and abrasion to be performed by TUD. The candidate will be fully integrated in the European project group and will be involved in the regular meeting of the partners.

Essential skills : Continuum mechanics, material law formulation, finite strain formulation, english.
Desired skills : Computational mechanics (FE), physics and chemistry of polymers

Research team  : this research will be part of the research activities of the “Materials and Structures” group of the LMA (18 permanent researcher, 5 engineers and 16 phd students)
