On the numerical modeling of granular material flows via the Particle Finite Element Method (PFEM)
International Journal of Solids and Structures, 2015 The aim of this work is to describe a numerical framework for reliably and robustly simulating the different kinematic conditions exhibited by granular materials while spreading ---from a stagnant condition, when the material is at rest, to a transition to granular flow, and back to a deposit profile.

Advances in the particle finite element method (PFEM) for solving coupled problems in engineering
, 2010 We present some developments in the formulation of the Particle Finite Element Method (PFEM) for analysis of complex coupled problems on fluid and solid mechanics in engineering accounting for fluid-structure interaction and coupled thermal effects, material degradation and surface wear.

Modeling Grinding Processes—Mesh or Mesh-Free Methods, 2D or 3D Approach?
Journal of Manufacturing and Materials Processing, 2022 The objectives of this study are mainly two: (1) to validate whether a single grain scratch process can be modeled in two dimensions under the assumption of plane strain, and (2) to select the best discretization approach to model a single grain scratch ...

An implicit locking‐free B‐spline Material Point Method for large strain geotechnical modelling
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 47, Issue 15, Page 2741-2761, 25 October 2023., 2023 Abstract The Material Point Method (MPM) has drawn great attention in the numerical modelling of large deformation, geotechnical problems. The popularity of MPM is mainly because its formulation shares significant similarities with the Finite Element Method.
