Abstract

Various types of behaviors of different soils have been predicted by using the FEM with comprehensive constitutive models developed in geomechanics. There are, however, still some problems for the large deformation analysis in the framework of FEM. Numerical instabilities arise due to the distortion of the FE mesh. SPH method is an effective method to solve large deformation problems by a mesh-less Lagrangian scheme. In this study, large deformation analyses of geomaterials using SPH method are carried out. Geomaterials are assumed to be a single-phase Bingham fluid with shear strength of soils. Based on the comparison with the simulated results using SPH method, the theoretical solutions and the existing simulated results, the applicability of SPH method for large deformation analysis of geomaterials is discussed.
