Dr Ahmad Varvani-Farahani from Toronto Metropolitan University, Canada presented an online course over three days to a group of participants from the USA.
This course was designed to build participants’ background from basics to the advanced level of fatigue fracture analysis. It covered practical-analytical aspects of fatigue failure and fracture mechanics for engineering components and structures subjected to various cyclic loading conditions. Typical fatigue problems were analyzed and methods of solution were discussed.
The course was designed for students needing to learn the fundamentals of fatigue fracture, as well as engineers practicing in various disciplines, including automobile, aerospace, pipeline and petroleum industries with a focus on stress analysis and failure of engineering components.
Course Topics
The topics covered included:
- Overview of stress and strain states, and materials properties
- Cyclic stress/strain- fatigue life
- The elements of elastic and plastic behaviour of materials
- Linear Elastic Fracture Mechanics (LEFM)
- Crack tip plasticity, R curves, and Fracture toughness
- Fatigue damage and cycle counting analyses
- Stress concentration factor, stress raiser effect on fatigue life
- Crack growth rate and fatigue life prediction
- The effect of mean stress on fatigue life of engineering components
- Fracture surface analysis
- Fatigue damage theories and approaches
- Cyclic plasticity and ratcheting theories
Presenter
Dr. Varvani is an associate professor who has worked in the area of fatigue and fracture of materials for the last 14 years. He is the author of over 25 refereed journal papers and the editor of three books on Fatigue and Fracture. He has also been a Fellow of Wessex Institute, UK since 2004.
