Effect of Notches

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.
