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

Knowledge and understanding
For a passing grade the student must

• be familiar with the diffrent types of fatigue and the basic mecanisms between fatigue.

• be familiar with engineering design against fatigue.

Skills and abilities
For a passing grade the student must

• demonstrate the ability to perform construction design against fatigue.
