Course Outcomes:
Students will be able to
- Apply the mathematical knowledge to define fatigue behaviours of the materials
- Identify the causes for the fatigue failure of the materials.
- Ability to analyse the fracture due to fatigue
- Select the testing method for the fatigue failure prediction of the materials.
- Solve the causes of the crack initiation & its growth.
- Select the materials with ability to with damage tolerant structures
