Contenus de l'unité d'enseignement
The class presents the basis of fracture mechanics. Failure of structures is explained by studying the physic of materials. This behavior is then modeled analytically. Finally numerical methods applied in fracture mechanics are presented.
Subjects covered by the lectures are
- Linear elastic fracture mechanics (LEFM)
- Non-linear fracture mechanics (NLFM)
- Fatigue
- Design approaches
- Recent numerical approaches
Acquis d'apprentissage (objectifs d'apprentissage) de l'unité d'enseignement
Through a deep understanding of the theory and the realization of a project, the student will be able to apply numerical tools to design structures and study crack propagation problems. In particular:
- He will have a deep understanding of fracture mechanics theories and will be able to summary, compare and explain them.
- He will have a deep understanding of the resolution methods of fracture mechanics 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 of fracture mechanics.
- He will be able to analyze and to evaluate (justify and criticise) these methods.
- He will be able to analyze new problems.

Mode d'enseignement (présentiel, à distance, hybride)
Face-to-Face: default mode
In case of remote teaching is mandatory
1) Recorded classes that could not be given face to face will be available in myUliege on a weekly basis.
2) Questions on this recorded class can be asked on the etaching day on the forum created in eCampus https://www.ecampus.ulg.ac.be.

- En présentiel

- En distanciel

Explications complémentaires:
Evaluation is based on the realization of a project (30%) related to the use / development of numerical methods specific to fracture mechanics and on an written examination (70%). 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. In order to have a total grade equal to or above 8/20, the student should obtain a grade equal to or above 8/20 for both the project and the exam.
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 requested.
Participation to the exam, to the guest lectures (if any), 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.
On site:
Written examination
In case of remote evaluation:
Same content. Exam will be given through eCampus. in particular:
- Questions will be obtained by eCamput 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.
