Course content

This course deals with fundamental and technical issues associated with designing and maintaining structures that resist failure from cyclic loading. Students will be taught the principles of analyzing failure of materials by fatigue including how fatigue behavior is characterized, how fatigue failure is predicted, the physical mechanisms responsible for fatigue failure of various materials with particular attention to metals and structural alloys, and how such behavior is related to the microstructure of the material. This course will also introduce key applications of fatigue design in industry including failure analysis, fatigue life calculations and experimental techniques and destructive and non-destructive methods of damage detection and characterization.
Main Topics:
- Cyclic deformation
- Fatigue crack initiation
- Stress-life fatigue behavior
- Strain-life fatigue behavior
- Fracture mechanics and fatigue crack propagation
- Environmental effects

Learning outcome

Knowledge :
- Fatigue mechanisms.
- Description of fatigue phenomenon.
– Fatigue life concept.
- Methodology for designing against fatigue.
- Methodology for fatigue-crack-growth analysis.

- Capability to use traditional methods for designing mechanical components against fatigue.
- Capability to use crack-growth analysis for life assessment of mechanical components containing cracks and crack-like defects.

General competence: To be capable to evaluate fatigue damage and to design machines and structures against fatigue and to predict the expected life of components in service.

Learning methods and activities

Lectures: Both presentations and blackboard are used in parallel. Teaching materials are provided through Blackboard. The purchase of text-books is not necessary for the successful completion of this course though it is encouraged for additional learning. Self-made notes during the lectures are encouraged since the lectures include the material and discussion which are hardly available in textbooks. 12 assignments will be given during the course, 9 being mandatory.

Compulsory assignments

  • Øvinger

Further on evaluation

Portfolio assessment is the basis for the grade in the course. The portfolio includes a final written exam (90%) and exercises (10%). The results for the parts are given in %-scores, while the entire portfolio is assigned a letter grade.

If there is a re-sit examination, the examination form may be changed from written to oral.

For a re-take of an examination, all assessments during the course must be re-taken.

Specific conditions

Exam registration requires that class registration is approved in the same semester. Compulsory activities from previous semester may be approved by the department.
