| Flipped Class | Structural dynamics Students will be led to reflect on the impact of dynamic phenomena on structural dimensioning. The common thread of the course is the concrete case study of actual seismic response of civil engineering structures. Students will implement regulations, acting as a design study engineer, while establishing the links with theoretical aspects. They will also be taught to use finite element software programmes to simulate the dynamic response of model structures.

| Flipped Class | Fracture mechanics Fracture mechanics is a basic tool for engineers in materials science and mechanical engineering. Following a presentation of the fundamental concepts and principle mechanisms of fracture, a detailed presentation will be given of linear fracture mechanics. The mechanics of non-linear fracture will be studied through the integral concept. Materials fatigue will be introduced in a heuristic manner. The course is based on theoretical sessions, supervised studies and practical courses. Chapter I : Introduction Chapter II : Linear elastic fracture mechanics I. Stress concentration II.
