Durability-aging of materials

One of the major problems linked to the use of various materials in our daily lives is their durability and therefore their degradation. In this course, we'll look at the issues surrounding the durability of materials (resources, reserves, criticality of materials, etc.) as well as the methodologies for studying durability (types of surface/volume aging, temporal extrapolation, multi-scale, combination of effects, experimental representation and industrial validation). This will then enable aging kinetics to be modeled using different models.

The different types of degradation affecting polymers will then be analyzed.

Finally, the ageing of different types of materials will be illustrated by various concrete case studies (concrete, ceramics, metals and elastomers).
