| Summary | This course provides ways to understand and describe mechanical behaviour of geomaterials from a computational modelling point of view. Plasticity theory and models as well as their integration algorithms will be presented for geomaterial constitutive behaviour. Discrete modelling will also be introduced as a complimentary approach to continuum theory. It will show how geotechnical engineering problems, such as consolidation, bearing capacity and slop stability, are modelled and solved using numerical approaches. |
