Title of Project

Development of damage accumulation fatigue model for low cycle fatigue

Advisor/s

Dr Greg Wheatley, Ricardo Branco, Fernando Antunes (University of Coimbra)

College or Research Centre

College of Science & Engineering

Summary of Project

The project involves the following:

  • obtain experimental results of the cyclic plastic behaviour for 3 strain ratios (e.g. R=-1; R=0; R=0.5) and study mean stress relaxation effects.
  • study the effect of loading history (step loading; periodic overloads, random loading, etc.) and sequence effects in smooth and notched geometries.
  • simulate the cyclic plastic response by developing a constitutive stress-strain model.
  • develop a damage accumulation fatigue model able to account for mean stress and loading sequence effects.

Key Words

low cycle fatigue; experiment; modelling; simulation
