Learning outcomes of the course :
|
| The objective of the course is to focus on analytical and computational methods for predicting the dynamic response of practical engineering structures. Special attention is devoted to aerospace, mechanical and civil engineering structures. |
|
Prerequisites and co-requisites/ Recommended optional programme components :
|
| This course requires basic knowledge of fundamental calculus and differential equations. The course also requires a mastery of introductory dynamics and mechanics. |
|
Planned learning activities and teaching methods :
|
| One project will be assigned to the students. It will give hands-on practice with methods used in structural dynamics (e.g., the finite element method, Newmark's algorithm, component mode synthesis). |
|
Mode of delivery (face-to-face ; distance-learning) :
|
| 1st Quadrimester |
|
Recommended or required readings :
|
| M. Géradin, D. Rixen

Assessment methods and criteria :
|
| The final grade will be based on the project report and the oral exam:
1. Group of students will be assigned a project. The grade will be based on the results and the quality of the report (scientific and technical content, conciseness, structuring of the written report and clarity of the text). An oral presentation will be organised at the end of the project.
2. The oral exam will consist in answering to questions on the theoretical concepts explained in the course.
The assessment is based on the weighted geometric average of the project and the oral exam. The final note is calculated as follows:
Final note = (Project)^(0.6) * (Theory)^(0.4) |
