Research InterestThe main area of my research is the fatigue and fracture of Ultra High Strength Steels (UHSS) and their weldments. This assessment covers the analyses from microstructural point of view to the macroscale where the microstructure does not have a big influence on the components failure. The concepts of fatigue and fracture will be applied through the experiments and numerical simulations. Methods, such as crystal plasticity finite element modeling, continuum finite element analysis, and stress/strain based approaches are used.
