| Course description | 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. |

Summary of Intended Learning Outcomes
The achievement of the learning objectives in this course will be measured through the students' ability to
- distinguish between different types of constitutive models and identify the appropriate model according to the soil types and loading conditions
- select the correct integration algorithm for a specific constitutive model
- understand basic concepts and models for discrete modelling
- understand numerical procedures and interpret the results in the geotechnical engineering context
- conduct computer simulations to solve geotechnical engineering problems using finite and discrete element methods |
