Abstract

In a quick flow of granular material, the initially densely packed material often starts to separate and its behaviour changes to that characteristic of a liquid and, at low enough density, to the state where grains are disconnected from the other grains (gaseous states). Modelling such a flow requires acknowledging the changes in the granular material, in particular noting the changes in the constitutive behaviour as well as having the capability to model large displacements and deformations. This study employs the Material Point Method to model the behaviour of granular material flow in transition from the solid to the gaseous state and from the gaseous to the solid state. The paper introduces modifications into the method to represent the changes in the granular material and the constitutive behaviour required for modelling of the granular material in the disconnected regime. This is the first step in application of the Material Point Method in modelling of the flow behaviour of granular material through its various states.
