Scientific Divisions

The research divisions of the Centre des Matériaux are dedicated to research on phenomena and processes in order to understand and predict the behaviour of materials and their functional and physical properties when subjected to mechanical, thermal, and severe environmental conditions. Material behaviour depends not only on composition but also on the elaboration and thermo-mechanical processes they are subjected to. Thus the optimisation of a given material depends on fabrication process parameters - for instance increasing alloy purity and controlling its microstructure through processing or heat treatments can considerably enhance its mechanical or functional properties - and on the knowledge of their behaviour under loading that simulates, as close as possible, in-service loading conditions. The notion of material performance has gradually given way to notions of reliability and environmental safety.

Recent developments in materials science and engineering are the result of cooperation amongst physical chemists, mechanical engineers, material scientists and numerical analysts. Such multidisciplinary environment characterises the Centre des Matériaux and is at the centre of the education of its students and young scientists. This diverse scientific culture has also led to significant progress by:

  • taking into account the behavioural laws for an increasingly broad range of materials (metals, ceramics, polymers, composites, fabrics, and multi-material systems) and assemblies (e.g. welded, brased and bonded) operating under complex loading conditions (e.g. high strain rate and temperature, creep, fatigue,...) in component and structural design;
  • integrating the notion of defects and damage into reliability assessments;
  • coupling multi-scale models with homogenisation techniques to predict the mechanical and physical properties of materials based on their actual microstructural characteristics;
  • developing and validating the concept of a "local approach" to fracture mechanics that integrates microstructural properties into damage and fracture processes.

Improved computer power now implies that industrial problems can now be solved taking into account aspects such as complex geometries, an accurate representation of materials microstructures, and complex mechanical, thermal and environmental loading conditions.
