Jérémy Bleyer granted an ERC Consolidator Grant

Jérémy Bleyer, a researcher at the Navier Laboratory, has received a grant from the European Research Council (ERC Consolidator Grant) for his AUTOMATIX project.

This grant is intended to support young researchers (7 to 12 years of experience after their PhD) and enables researchers to consolidate their research team and continue to develop their career.

AUTOMATIX: Automating Material modeling for composable and learnable behaviors

The AUTOMATIX project aims to transform the way in which the behavior of materials in solid mechanics is modeled and simulated. Accurately representing complex phenomena (deformations, damage, environmental or microstructural effects) remains a major challenge in many fields of application today. AUTOMATIX draws on recent advances in machine learning to automatically build behavior models directly from experimental data. Unlike current approaches based on the use of “black box” neural networks, the project proposes to integrate well-established physical and mathematical knowledge in mechanics into the very heart of the learning architecture. This hybrid approach makes it possible to obtain more reliable models that are consistent with fundamental laws and require less data for training.

One of the major outcomes of the project will be the creation of a high-performance, modular, open-source library dedicated to material modeling and making full use of modern machine learning technologies (automatic differentiation, GPU computing, optimization methods). AUTOMATIX will find direct application in the modeling of 3D printed concrete structures at the Navier laboratory, an emerging technology that requires models capable of capturing complex phenomena related to layer-by-layer deposition, material curing, and crack formation. The project thus aims to provide the academic and industrial worlds with flexible and powerful digital tools to accelerate the development of safer, more efficient, and better controlled materials and structures.
 

Jérémy Bleyer is an "Ingénieur en Chef des Ponts et Chaussées", HDR researcher at the Navier Laboratory at the School since 2017, and lecturer at the École Polytechnique since 2020. His research interests include theoretical and numerical mechanics of solids, in particular modeling of structural failure (plasticity, damage). He is also heavily involved in the development of open-source numerical tools. He was awarded the Jean Mandel Prize in 2023.
