About this position
This postdoctoral position is part of the ANR PRME LINEN project, which brings together several researchers at the École nationale supérieure des mines de Saint-Étienne to study the manufacture of structural composite parts based on flax fibres.
The project focuses on the numerical modelling of resin infusion into flax-fibre composite preforms, with the aim of understanding how the anisotropic and heterogeneous organisation of fibre tows influences resin flow at the mesoscale.
The appointed postdoctoral researcher will develop 3D finite-element simulations based on a Stokes-Darcy coupling and an orthotropic permeability tensor. The work will investigate how local variations in fibre volume fraction affect permeability, preferential flow paths, and capillary effects.
Simulations will be carried out using the Cœur finite-element code, with PETSc and preconditioned iterative solvers adapted to large-scale problems. The initial phase will study idealised unidirectional, quasi-unidirectional, and woven architectures using a Level-Set representation. If feasible, the second phase will move toward realistic mesostructures reconstructed from µ-CT images.
The postdoctoral researcher will also contribute to the development and validation of the numerical strategy and work in close interaction with the experimental and numerical activities of the other project tasks.
