What you will learn
Providing a practical understanding of fatigue and fracture calculations, this course is intended for engineers who are required to perform such calculations, or who specify or evaluate testing and draft fatigue or fracture portions of design requirements.
- Explain the underlying assumptions and limitations of fracture mechanics
- Describe the process for material selection for fatigue and fracture resistance
- The difference between various Fatigue Life techniques
- The technologies behind Fracture Mechanics
- How and when to use the different types of techniques
- The difference between a Fatigue and a Fracture Mechanics approach, and when to use each of them.
- The importance of accurate stresses for Fatigue Life prediction.
