Structural dynamics
Goals
The dynamic analysis of structures using modal synthesis and finite element methods has found a large number of industrial applications (aeronautics, automotive, shipbuilding, rail, civil engineering). The main goal of this course is to present these methods in a general framework by carrying out in parallel and in interaction a numerical approach and an experimental approach based on vibratory tests. Model correction and the influence of damping are also discussed.

Sustainable development
DD&RS level 1
Activity contextualised through environmentally sustainable development and social responsibility and/or supported by examples, exercises, applications.
Programme elements related to sustainable development goals
Computer modeling of structures is one of the pillars of design and optimization. It is necessary to achieve sustainable development objectives, in terms of material use, energy consumption, and sustainability.
