Beskrivning

Research topics include materials degradation and non-destructive testing. In materials degradation, focus is on energy materials (nuclear, in particular), fatigue, thermal fatigue and residual stresses. Recent research focuses on measuring and understanding weld residual stresses in complex nuclear welds, dissimilar metal welds and weld repairs and their possible relaxation during in-service use.

In non-destructive testing, the research focus is on reliability assessment of various NDT methods, probability of detection determination and advanced NDT data processing.
