Prerequisite or corequisite units are presented within each program
Learning unit contents
This course provides a solid background in vibration theory for engineering applications.
Course outline
- Introduction and analytical dynamics of discrete systems
- Undamped vibrations of n-degree-of-freedom systems
- Damped vibrations of n-degree-of-freedom systems
- Continuous systems: bars, beams and plates
- Approximation of continuous systems by displacement methods; Rayleigh-Ritz and finite element method
- Solution methods for the eigenvalue problem
- Direct time-integration methods
- Introduction to nonlinear dynamics
Learning outcomes of the learning unit
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.
Prerequisite knowledge and skills
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).

Assessment methods and criteria
The final grade will be based on the project report and a written exam:
1. The project has to be done individually or by group of maximum 2 students. 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 written exam will consist in answering to questions on the theoretical concepts explained during the lectures. No document is allowed for the written exam.
The assessment is based on the weighted geometric average of the project and the written exam. The final note is calculated as follows:
Final note = (Project)^(0.6) * (Theory)^(0.4)
There is no partial exemption in case of failure.

Assessment methods
The assessment will be based on the project report and a written exam.
1. The project assignment will be communicated at the end of the first session. The project has to be done individually. The assessment 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 during the exam session through the Lifesize platform according to a schedule established by mutual agreement. The total duration of the oral exam will be 30 minutes and will consist of 5 minutes of presentation of the results, 20 minutes of questions/answers and 5 minutes of deliberation.
2. The written exam will be organised as a remote review in an open-book format through eCampus. It will consist in answering to multiple choice questions on the theoretical concepts presented during the lectures. The questionnaire will be available at the date and time scheduled in the exam timetable. Students will have a limited amount of time to answer the questions.
The assessment is based on the weighted geometric average of the project and the written exam. The final grade is calculated as follows:
Final note = (Project)^(0.6) * (Theory)^(0.4)
