Course Objective
“Provides a comprehensive overview of fatigue mechanics for engineers, and the knowledge and tools to help engineers design against fatigue failure.”
About the Course
Did you know that the number of structural failures due to fatigue is much larger than due to static overload? Managing and preventing problems due to metal fatigue should be considered a key capability of a structural engineer. Safe operation of your structural asset is important to you, you want to avoid your structure collapsing.
This course will give you a detailed overview of fatigue; practical advice and guidelines are given, and justified based on the theoretical background. After this course you will know exactly what fatigue is, what loads are causing fatigue, how you can control fatigue, how you can improve your design and which factors are good and bad for fatigue. With this knowledge you can determine a safe fatigue life for your structure.
The course consists of 14 online modules based on video lectures. Participants also gain access to a technical archive of fatigue related articles by the instructor.
After the course you have unlimited access to the course for 1-year, including any new course material. This allows you to perform modules again should you need to refresh your knowledge for your projects.

Excellent Course for Beginning
Introduction to Fatigue course from Fatec Academy was very helpful for me to deeply understand fundamental subjects about fatigue analysis. Some details in this course are really hard to find by own effort. Therefore, it is very beneficial to take this course for beginning fatigue studies.
Great fatigue course with focus on application of the theory
The fatigue course and additional modules offer an extensive learning experience in applied fatigue analysis. There is a lot of instantly applicable knowledge available, and the theory of fatigue is explained very accessibly. To gain the full benefit of the course, a foundation of solid and structural mechanics should be present in the reader’s mind, however even without such a background, the important points and concepts can be understood.
Covering the fatigue life from initiation to macro-crack growth, the practical structural and design engineers needs are fully covered. It doesn’t cover mathematical derivations much, e.g. crack tip stress fields. This is not a problem though, they can be found in a lot of reference books and obviously not the aim of the course.
The additional modules give insight into multiaxial fatigue and additional material as testing and damage tolerance with a focus on the aeronautical side.
Personally, I found the didactical method, how concepts are brought across to the reader very well done, and especially enjoyed the multi-axial fatigue module.
Overall it is clear to see that a lot of thought and years of experience have contributed to the module content. The information is accessible and the link to practical applications is never far.
I would highly recommend the course for engineers new to or already working in mechanical fatigue and students at graduate level.
