Modelling the mechanical behaviour of clay using particle-scale simulations

de Bono, John; McDowell, Glenn

Abstract

This paper demonstrates the latest developments in particle-scale modelling of a clay. It shows that by creating an initial sample of platelets featuring aggregated stacks, excellent macroscopic behaviour is achieved. This approach is justified by examining SEM images of clay slurries, and is consistent with the behaviour of real clays. The use of aggregated stacks allows a wider range of platelet interactions and micro properties to be simulated and investigated, and significantly, enables interactions to be modelled that are based on a range of real measurements obtained from surface force experiments.
