Please note! Course description is confirmed for two academic years, which means that in general, e.g. Learning outcomes, assessment methods and key content stays unchanged. However, via course syllabus, it is possible to specify or change the course execution in each realization of the course, such as how the contact sessions are organized, assessment methods weighted or materials used.

LEARNING OUTCOMES

After the course, the student
- understands the material behaviour under cyclic loading and fatigue phenomenon.
- can identify the main affecting factors and requirements for fatigue assessment.
- understands the main modelling principles and assumptions used in common fatigue approaches.
- can apply a selected fatigue approach for structural design.

CONTENT, ASSESSMENT AND WORKLOAD

Content
  • valid for whole curriculum period:

    The course starts with an introduction to the fatigue phenomenon and fatigue loading. The theory phase covers the modelling principles, followed by different modelling methods: stress and strain-based approaches and fracture mechanics. The analysis methods are applied to the practice through weekly assignments and fatigue assessment of the selected structural detail or component (Project work). In addition, the course covers the basics of residual stress effect, fatigue of welds, multiaxial fatigue and statistical aspects.

Assessment Methods and Criteria
  • valid for whole curriculum period:

    Assignments, exam, and optional project work. The grading will be based on assignments (50%) and exam (50%).

Workload
  • valid for whole curriculum period:

    Lectures: 24h
    Instructed exercises: 12h
    Assignments&project: 50h
    Studying materials: 40h
    Preparing for exams: 10h
