AbstractThis PhD work aims to characterize the mechanical behaviour of various refractory concretes at high temperatures (bending, compression and tension tests up to 1500°C), then to test them by instrumented thermal flame shocks (temperature measurements, displacements by image correlation,...). These results would allow to propose a thermomechanical behaviour model (finite element calculation) taking into account, in addition to elasticity, damage and creep, the sudden ruptures sometimes spontaneously induced by phase changes and internal pressures caused by the water exhaust during rapid temperature increases.
ProfileEngineer and / or Master of Science - Good level of general and scientific culture. Good level of knowledge of French (B2 level in french is required) and English. (B2 level in english is required) Good analytical, synthesis, innovation and communication skills. Qualities of adaptability and creativity. Teaching skills. Motivation for research activity. Coherent professional project.

Prerequisite (specific skills for this thesis): Strong knowledge of materials and their mechanical behaviour. Particular experience in the field of concrete and/or finite element analysis would be particularly appreciated.
