In this video I discuss the mechanisms behind fracture, and how S-N curves can be used to predict the fatigue life of a component. Crocodile Dundee ‘icon’ dies, aged 90 Resident highlights ...

The contents have been developed as course notes for training courses presented to engineers who need to apply fatigue knowledge in engineering design, fatigue testing and failure investigation.

The lower S-N curves show the difference in the behavior of this type of alloy and a carbon steel. The carbon steel shows a "fatigue limit" below which its fatigue life tends to infinity. An aluminum ...

The S-N curve shows the performance of some uniaxial fiber-reinforced composite materials ... Compression testing shows a stress level decrease of about a factor of two for the same fatigue life.
