Research and Professional Activities 1) Fatigue and Fracture of Materials and Components The study of fatigue failure and brittle fracture in metals and other materials. Fatigue crack propagation and fracture mechanics; fatigue life prediction of components; use of finite element analysis; the behaviour of stress concentrations. 2) Forensic Engineering Failure analysis and metallurgical examination of components for forensic purposes. Consultancy work to engineering companies on component design and life prediction. 3) Bioengineering The assessment of materials for use in human-body implants and other biomaterials. Fatigue and fracture properties of bone in humans and animals.
