| 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. |

Learning Outcomes
On completion of this course, the student will be able to:
- Distinguish between different types of constitutive models and identify the appropriate model according to the soil types and loading conditions
- Use basic concepts and models for discrete modelling to calculate a dynamic discrete process
- Interpret the results of numerical procedures and in the geotechnical engineering context
- Conduct computer simulations to solve geotechnical engineering problems using finite and discrete element methods
