A Meshfree Method for Modeling the Impact of Landslide Activity
This paper presents a two-field semi-Lagrangian reproducing kernel particle method for landslide simulations. The method combines advantages of Eulerian and Lagrangian formulations in that state variables follow material points while the approximation functions are updated in the current configuration to allow extreme deformation and material separation. The Biot theory is employed to describe poromechanics of geomaterials. A Drucker-Prager model with damage is adopted to represent constitutive model of solid phase of porous media. In addition, a variationally consistent integration (VCI) scheme is employed in the two-field semi-Lagrangian formulation to enhance solution accuracy. The proposed method is verified with several numerical examples and its applicability of simulating landslide events is validated with an experimental result.
