What will I learn?
Day 1Failure case studies:
- Examples of engineering failures
- Contributing factors and lessons learnt, especially with respect to welded structures
Fitness-for-purpose methods:
- Concept of fitness-for-purpose methods and engineering critical assessment (ECA)
- Key factors affecting structural integrity
Fracture mechanics theory:
- Main principles of fracture (for driving force and fracture toughness): K, CTOD, J
- Linear elastic and elastic-plastic fracture mechanics (LEFM and EPFM)
Non-Destructive testing (inspection):
- Role of NDT in ECA
