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
