Multiphysics and multiscale approaches to heterogeneous materials
The aim of this area is to characterise and model the mechanical behaviour, damage and wear of heterogeneous materials in relation to their conditions of use, whether these be structural materials, civil engineering materials, friction materials or soft biological tissues for medical engineering.
The aim is to meet the following 4 challenges:
- improve safety, reliability and sustainability in transport,
- reduce consumption of materials and energy,
- reduce environmental pollution,
- increase the effectiveness of patient care, health and well-being.
These actions, focused on Transport, Energy and Health, are in line with the major research programmes (ANR, ADEME, ELSAT 2020, etc.) and the challenges of ‘Intelligent, green and integrated transport’, ‘Safe, clean and efficient energy’ and ‘Life, health and well-being’ and the European Horizon H2020 programme. The health actions are also in line with the expand ambitions of the ‘Precision Human Health’ Hub of the ULNE Lille Nord-Europe I-SITE.
The complexity of the materials in question and their stresses has led those involved in this area to develop original and remarkable multiphysics and multi-scale experimental approaches to understanding behaviour and performance under conditions representative of their use. The aim over the next 10 years is to pursue these approaches, and more specifically the research activities will focus on 4 themes:
- Mechanisms of fatigue, damage and failure of structural materials
- Thermo-hydromechanical and chemical behaviour of materials
- Friction materials under extreme stress
- Soft biological tissues for medical engineering
To carry out the actions in this area, Centrale Lille will draw on its teams at the Mechanics, Multiphysics and Multiscale Laboratory (LaMcube) and its remarkable experimental resources, such as the ISIS4D X-ray imaging platform, the TriboFrein tribology platform, the Civil Engineering multiaxial mechanical testing platform and the CISIT Transport Hall, as well as the YaDICs digital image correlation platform and the Centrale Lille research laboratory, TriboFrein tribology, multiaxial mechanical testing in civil engineering and the CISIT Transport Hall, as well as the YaDICs digital image correlation platform and the SWIT_Lab joint research laboratory (LaMcube, LAMIH, MG Valdunes, CNRS).
