Jean-François Barthélémy

Researcher · Cerema / UMR MCD

I work at the intersection of theoretical mechanics, materials science and scientific computing, at Cerema (Centre d’Études et d’Expertise sur les Risques, l’Environnement, la Mobilité et l’Aménagement) and within the UMR MCD (Matériaux et Durabilité des Constructions, Université Gustave Eiffel).

Research interests

Micromechanics and homogenization

Analytical and semi-analytical methods for predicting the effective properties of heterogeneous materials — composites, geomaterials and cracked media.

Eshelby-based models

Dilute, Mori–Tanaka, self-consistent and generalized self-consistent schemes for ellipsoidal and crack-like inclusions.

Nonlinear and viscoelastic behavior

Extension of homogenization methods to nonlinear elasticity and to linear, possibly ageing, viscoelasticity.

Scientific software

Open-source libraries in Julia and C++ for computational micromechanics — see Software.

Software

I develop and maintain open-source libraries for computational micromechanics, most of them gathered in the MicroPoroChemoMechanics Julia organization, alongside the C++/Python library echoes.
