Report My doctoral work is focussed on the influence of the complex mechanical behavior of soft soils on mechanized tunneling processes. Precise prognoses for the settlements of the ground surface require an adequate constitutive model. To improve my constitutive soil model, I applied for an international research exchange program in the US. It took place between February and May, 2014. I worked with Prof. Dafalias (Chair for Structural Mechanics and Geomechanics at the University of California, Davis) and Prof. Kaliakin (Chair for Geotechnical Engineering at the University of Delaware), as they are leading scientists in the field of computational geomechanics. Furthermore, they are the developers of a plasticity theory, which is the basis for my evolutionarily formulated constitutive soil model. The collaboration resulted in the extension of my model to a more sophisticated model, as well as its efficient numerical implementation to a finite element code.
