Bakgrunn og aktiviteter
- Various projects concerning soil modelling. This includes:
- Modelling and understanding creep in soft clays and other aspects of soil behaviour.
- Development and implementation of a number of soil models, including the NGI-ADP model that is now part of a commercial finite element program (www.plaxis.nl).
- Progressive failure in sensitive clays. This includes:
- Work with the implementation of a regularisation technique for modelling of brittle material behaviour in finite element calculations
- Back calculations to landslides involving quick clay
