N2 - To investigate open ended pile-chalk interaction and axial load transfer mechanisms during installation, a coupled DEM (discrete element method) – FDM (finite differential method) model is used. To capture the complex behaviour of chalk a newly developed DEM bond damage contact model for highly porous soft rocks is used. The DEM model is calibrated to capture experimental data of St Nicholas-at-Wade (SNW) chalk from the literature. The model is then used to simulate model pile installation experiments on the same chalk.
