Module Aims
The aim of this module is to enable students to carry out appropriate analysis to apply to designs where failure due to fatigue may be an issue. The analysis of cracks in structures allows the students to make informed decisions as to appropriate actions that can be taken to prevent unwanted catastrophic failure.
Content Summary
Fatigue:
Fatigue failure, testing, and standards.
Factors affecting fatigue (surface finish, size, stress concentrations, etc).
Effects of non-zero mean loads (Gerber, Goodman, Soderberg).
Cumulative fatigue damage (Miner’s rule, Manson’s rule).
Combined torsional and bending fatigue.
Fracture:
Fracture mechanics, testing, and standards
Griffiths approach
Stress intensity factor
Fracture toughness
Fatigue crack growth
