Effect of pre-strain of high cycle fatigue life

Title of Project

Effect of pre-strain of high 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 the effect of different pre-strain histories (tensile, or compressive, or biaxial, or several). Compare the fatigue life (S-N curves) for the different pre-strain histories (smooth and/or notched specimens). Develop a model to predict the fatigue life (using LCF properties for the same material). Analysis of failure mechanisms from fracture surfaces and microstructure features.

Key Words

pre-strain; high cycle fatigue
