About the course
Notches and other geometric discontinuities significantly influence the fatigue life of structural components, often serving as the starting point for crack initiation. This course focuses on understanding how stress concentrations impact fatigue performance, exploring the fatigue limits of structures, and interpreting S-N curves for practical applications.
Through a combination of theoretical insights and practical examples, participants will gain a deeper understanding of how to assess and mitigate the effects of notches in design and analysis.
Key topics include:
Stress concentrations and their impact on fatigue
Fatigue limit considerations for structural components
Understanding and applying S-N curves for structural analysis
This course is ideal for engineers seeking to enhance their design practices and improve the fatigue resistance of components exposed to stress concentrations.

Learning Outcomes
After this course, you...• have seen in depth the steps in the fatigue mechanism, from crack initiation and crack growth, to fatigue failure.
• are familiar with an S-N curve, and the impact of different factors such as loading type, component size and material strength on the fatigue life.
• understand how stress concentrations factors can be calculated and used to determine the effect of notches and other geometric features on the fatigue life.
• can calculate the fatigue life for a component under different loading conditions and the impact of safety factors.
• will have seen the underlying experimental tests and theory which forms the basis of the fatigue design S-N curves and stress concentration factors.
