General Information

Elective for: F5, M4-pu, M4-bem
Language of instruction: The course will be given in English on demand

Aim

The aim of the course is to describe the physical mechanisms behind fatigue, and the methods that are used in design against fatigue.

Learning outcomes

Knowledge and understanding
For a passing grade the student must

• be familiar with the different types of fatigue, the basic mechanisms behind fatigue and be able to use commonly accepted methods of design against fatigue.
• be familiar with engineering design against fatigue.

Competences and skills
For a passing grade the student must

• demonstrate the ability to perform construction design against fatigue and to recognize situations and mechanisms relevant to fatigue.
