Established: 2021-06-10

Established by: Department of Engineering Science

Applies from: V22

Learning outcomes

After completion of the course, the student should be able to:

• explain the basic mechanisms for fatigue damage.
• explain how different factors influence the fatigue life.
• show how fracture mechanics principles can be used in fatigue assesments.
• perform a simplified fatigue life assessment.
• explain how materials data for fatigue life assessment is generated.

Entry requirements

Bachelor of Science degree in materials science and engineering, mechanical engineering, chemical engineering, manufacturing engineering, production technology, or equivalent. In addition, at least 7.5 HE credits in materials science, at least 15 HE credits in mathematics, and English B/English 6 or equivalent are required.

The forms of assessment of student performance

Individual written exam. Individual quiz. Written assignment in group.

Course contents

• Introduction to fatigue and fracture mechanics.
• Micro- and meso-mechanical backgrounds to the understanding of fatigue.
• Fatigue properties observed on the macroscopic level.
• Fatigue analyses for long lives-the stress based approach.
• Fatigue with influence of plasticity. The strain based approach (LCF).
• A fracture mechanics approach to fatigue.
• Fatigue damage with variable amplitude loading.
• Evaluation of material properties.
• Means to avoid or minimize risks for fatigue damage in the design process.
