DESCRIPTION:Fluidisation problems in granular soils are of great interest 
 in areas such as geophysics\, engineering applications and industrial proc
 esses. Numerical modelling is very important to understand the mechanics a
 nd to predict failures that involve fluidisation. It is difficult to use m
 esh based methods such as the finite element method which is widely used i
 n geotechnical engineering to model dynamic behaviour of these failures. H
 owever recent advances in particle methods that are derived in continuum m
 echanics framework allow us to model large deformations inherent to fluidi
 sation problems.\n\nThis presentation will describe how the Material Point
  Method (MPM)\, a recent numerical method which combines the best aspects 
 of Lagrangian and Eulerian discretisations\, has been applied to model dry
  granular flows. This talk will also cover the proposed coupled consolidat
 ion formulation for MPM to model saturated soil with particular attention 
 to seepage failures. Results from MPM will be discussed along with the res
 ults obtained from experimental\, analytical and other numerical methods.\
