In my research, I have mainly worked on high-temperature applications such as gas turbines and jet engines. The high load and harsh environment in these machines requires engineering materials of extraordinary mechanical properties such as good creep strength, excellent high-temperature strength and sufficient fatigue strength. It is also necessary to have reliable, accurate and applicable material models and fatigue models in order to design safe machines. Development of such models often relies on testing and characterisation of materials combined with numerical modelling of stress and strain as well as the use of fracture mechanics.
Robert Eriksson
Professor
My research lies between materials science and solid mechanics and includes the study of e.g. mechanical properties, material fatigue, fracture mechanics, materials testing and material modelling.
Material fatigue at high temperature
Materials carrying cyclic load at high temperature are particularly susceptible to fatigue. Material fatigue involves the development of damage in the material, crack initiation in damaged regions, crack growth and, eventually, final rupture.
