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 courses based on video lectures. Participants also gain access to a technical archive of fatigue related articles by the instructor. All training content is provided through your EngineeringTrainer account.

Learning Outcomes
After this course, you...• have a fundamental understanding of high cycle fatigue, and how to interpret the fatigue calculation methods in industry standard codes.
• know how to identify fatigue critical locations, and are familiar with the analysis methods (both analytical and FEA) to predict the fatigue life.
• understand the limitations of fatigue life analysis and the effect of scatter.
• have seen how fatigue behaviour is impacted by the mean stress, the surface condition and surface treatment.
• understand how fatigue behaviour is impacted by the environment, such as temperature and corrosion.
• have seen the concepts for damage accumulation and combined fatigue loading.
• understand how to test structural components for fatigue.
• know the crack growth mechanism and can calculate the residual strength.
