Effect of strain ratio on constant amplitude low cycle fatigue life

Title of Project

Effect of strain ratio on constant amplitude low cycle fatigue life

Advisor/s

Dr Greg Wheatley, Dr Ricardo Branco University of Coimbra

College or Research Centre

College of Science & Engineering

Summary of Project

Study fatigue damage accumulation under constant amplitude loading. Test different fatigue damage accumulation laws (linear and non-linear). Predict fatigue life using fatigue parameters determined at CA (stress-based, strain-based, energy-based). Develop a mixed numerical-experimental model to predict the fatigue life.

Key Words

strain ratio; constant amplitude; low cycle fatigue
