The knowledge of different constitutive models and their applications are state of the art in geotechnical design. After a general introduction to computational geotechnics and constitutive models, the participants will learn basics of Critical State Soil Mechanics. Tools for parameter calibration of selected constitutive models (elasto-plastic and hypoplastic constitutive models) will be introduced and complemented by simulations of element tests. The influence of the individual material parameters and the individual models is clearly visualized in the element tests. Based on this, the modeling of different boundary value problems with different models and different FE software packages is a main focus of the Summer School.
