Teaching in the second semester

Schedule

Schedule online

Units courses prerequisite and corequisite

Prerequisite or corequisite units are presented within each program

Learning unit contents

The purpose of the lectures is to introduce the design of semi monocoque structures used in aeronautics. Three domains are studied:

  • Structural idealization: Analytical models of wing and fuselage based on thin-walled section beam.
  • Thin structures models: Theory and introduction to finite-element model of plates and shells.
  • Introduction to buckling of thin structures.

Learning outcomes of the learning unit

The student will have acquired the methodology required to conduct a preliminary study in the context of aircraft structures. In particular:

  • He will have a deep understanding of the thin-walled beams and thin structures theory and will be able to summary, compare and explain them.
  • He will have a deep understanding of the resolution methods of thin-walled beams and thin structures buckling problems, and will be able to summary, compare and explain them. He will also know their application range.
  • He will be able to apply the resolution methods to classical problems.
  • He will be able to analyse and to evaluate (justify and criticise) these methods.
  • He will be able to analyse new problems.

Prerequisite knowledge and skills

Good knowledge in

  • Solid mechanics
Elementary knowledge in
  • Finite-element method
  • Aerodynamics
Mastering Catia or a FE software

Planned learning activities and teaching methods

Exercises and personal project. A major part or the totality of the personal project is achieved in the context of the APRI0004 class.

Mode of delivery (face-to-face ; distance-learning)

Face to face

Recommended or required readings

Assessment methods and criteria

Evaluation is based on the realization of a project (30%) related to the design and/or modeling of a semi monocoque structure and on a written examination (70%). In order to obtain a grade larger or equal to 8/20, grades of at least 8/20 should have been secured for the both the project and written examination parts separately. If one of the two parts has been granted with a grade lower than 8/20, this grade will be used as a final grade. In case of a resit, if a grade of at least 10/20 has been given to the project, only the written examination will be redone. The previous rule of securing 8/20 grades for both parts separately will still hold.
A major part or the totality of the personal project is achieved in the context of the APRI0004 class. The grade of the related part of the APRI0004 project will be used for this class project grade.
The examination is based on the whole content of the class. Problems similar to the ones studied during the classes, and new problems will be part of the questions. Justification using the theoretical content is also asked.
Participation to the exam, to the guest lectures, and achievement of the project are mandatory. The student who does not attend to compulsory sessions or who does not delivered the assignments on time will not be allowed to present the exam.

Adaptation of teaching commitments following the COVID-19 pandemic for the May-June 2020 session

Teaching methods implemented : distance-learning

1) Recorded classes that could not be given face to face are made available in myUliege on a weekly basis.
2) Questions on this recorded class can be asked on the next Wednesday 2pm on the forum created in eCampus https://www.ecampus.ulg.ac.be.
3) Questions on the project can be asked on Wednesday 2pm on the forum created in eCampus https://www.ecampus.ulg.ac.be

Assessment subjects

1) Examination will focus on lectures:

2) Nothing has changed for the project assignement.

A major part or the totality of the personal project is achieved in the context of the APRI0004 class. The grade of the related part of the APRI0004 project will be used for this class project grade.
The examination is based on the updated contentof the class. Problems similar to the ones studied during the classes, and new problems will be part of the questions. Justification using the theoretical content is also asked.
Exam will be given through eCampus. in particular:

  • Questions will be obtained by eCamput or by e-mail the day of the exam;
  • Students will have to answer to the questions on separated sheets of paper; scan them; and upload them on eCampus;
  • There will be a limited time for each question.
