Please note! Course description is confirmed for two academic years (1.8.2018-31.7.2020), 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 main affecting factors and requirements for fatigue assessment.
- understands the main modelling principles and assumption used in common fatigue approaches.
- can apply selected fatigue approach for structural design.

CONTENT, ASSESSMENT AND WORKLOAD
Content
Valid 01.08.2020-31.07.2022:
The course will start with an introduction of fatigue phenomenon and fatigue loading. The theory phase covers the modelling principles and it is followed by different modelling methods: stress and strain -based approaches and fracture mechanics. The analysis methods are applied to the practise thorough the fatigue assessment of the selected structural detail or component (Project work). Project works is performed trough weekly-based assignments. In addition, the course covers the basics of residual stress effect, fatigue of welds, multiaxial fatigue and statistical aspects.
Applies in this implementation:
The course is organized using online tools, e.g. Microsoft TEAMS.
Assessment Methods and Criteria
Valid 01.08.2020-31.07.2022:
Assignments, project work and exam. Grading will be based on assignments&project work (50%) and exam (50%).
Applies in this implementation:
Student should get half of maximum point for assignment, project work and exam in order to pass the course.
