Abstract
This paper presents the recent development of the smoothed particle hydrodynamics (SPH) method for accurate predictions of granular flows. Granular materials are described within the classical plasticity theory framework, while the large deformation and flow behaviour of the materials are simulated by the mesh-free SPH. To improve the accuracy of SPH for the post-flow prediction at which stress fluctuation under large shear deformation is usually observed, a stress regularisation technique recently proposed by the authors is adopted. Through several numerical validations with experiments under 2D and 3D conditions, the proposed SPH model shows significant improvements in the accuracy and stability of SPH not only for simulations of granular flows, but also for general applications for solid materials.
