The Finite Element Method (FEM) is widely used in the simulation of
geotechnical applications. Owing to the limitations of FEM to model
problems involving large deformations, many efforts have been made to
develop methods free of mesh entanglement. One of these methods is the
Material Point Method (MPM) which models the material as Lagrangian
particles capable of moving through a background computational mesh in
Eulerian manner. Although MPM represents the continuum by material
points, solution is performed on the computational mesh. Thus, imposing
boundary conditions is not aligned with the material representation. In
this paper, a non-zero kinematic condition is introduced where an
additional set of particles is incorporated to track the moving
boundary. This approach is then applied to simulate the seismic motion
resulting in failure of slopes. To validate this simulation procedure,
two geotechnical applications are modelled using MPM. The first is to
reproduce a shaking table experiment where the results of another
numerical method are available. After validating the present numerical
scheme for relatively large deformation problem, it is applied to
simulate progression of a large-scale landslide during the Chi-Chi
earthquake of Taiwan in which excessive material deformation and
transportation is taking place. (C) 2016 Elsevier Ltd. All rights
