STAGE BAC +5 - Numerical Modeling for Bitumen Lifetime Prediction

Beschreibung:

Country France City SOLAIZE Workplace location SOLAIZE-CHEMIN DU CANAL(FRA) Employer company TotalEnergies OneTech Domain Research Innovation&Developpt Type of contract Internship Experience Less than 3 years

Context & Environment

Within the OneTech branch of TotalEnergies, you will join the Solaize Research Center, located 15 minutes south of Lyon.
The site brings together more than 300 researchers in a green environment 🌳.
It is one of TotalEnergies' main R&D centers, specifically dedicated to :
* Developing solutions as well as measurement and control tools for greenhouse gas emissions
* Formulating low environmental impact and decarbonized products for thermal and electric mobility, as well as for industry (non-fossil fuels from renewable sources, lubricants, heat transfer fluids, bitumen, etc.)

Activities

TotalEnergies is committed to becoming a leader in sustainable mobility. This includes improving the longevity of road infrastructure, particularly bitumen-a key product in our portfolio. To support this ambition, we are developing numerical models to quantify and predict bitumen lifespan on roads, a strategic priority for the Company. The numerical model is multiphysics, coupling mechanical, thermal, and chemical phenomena, with finite element discretization. We are seeking a trainee engineer to join our research and development team.
In this role, you will contribute to the deployment and enhancement of our road performance and durability prediction model through the following missions :
* Operate and analyze the numerical model and its modules (fatigue, ageing, micromechanics)
* Apply the model to various bitumen formulations study (conventional binders, polymer-modified, recycled, biosourced)
* Identify key influencing model input parameters and conduct parametric analyses on material properties
* Apply inverse modeling to guide formulation strategies for target performance metrics
* Develop a workflow to automate simulations and integrate experimental data and numerical modules
* Contribute to technical reporting and present findings
* Write a formal internship report with clear conclusions

Resources and tools used :
* COMSOL Multiphysics software
