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 ...

Multi-fluid flows with the Particle Finite Element Method [PDF]
Computer Methods in Applied Mechanics and Engineering, 2009 Particle methods are those in which the problem is represented by a discrete number of particles. Each particle moves accordingly with its own mass and the external/internal forces applied on it. In this paper the Particle Finite Element Method based on finite element shape functions is used to solve the continuous fluid mechanics equations in the case

Shockwaves in spillways with the particle finite element method [PDF]
Computational Particle Mechanics, 2020 Changes in direction and cross section in supercritical hydraulic channels generate shockwaves which result in an increase in flow depth with regard to that for uniform regime. These disturbances are propagated downstream and need to be considered in the design of the chute walls.

Stress Recovery for the Particle-in-cell Finite Element Method
Physics of the Earth and Planetary Interiors, 2020 The interelement stress in the Finite Element Method is not continuous in nature, and stress projections from quadrature points to mesh nodes often causes oscillations. The widely used particle-in-cell method cannot avoid this issue and produces worse results when there are mixing materials of large strength (e.g., viscosity in Stokes problems ...

Adaptive Particle Finite Element Method (A‐PFEM) in Metal Cutting Processes [PDF]
PAMM, 2021 AbstractMachining is very common in industry, e.g. automotive industry and aerospace industry, which is a nonlinear dynamic problem including large deformations, large strain, large strain rates and high temperatures, that implies some difficulties for numerical methods such as Finite element method.

The Particle Finite Element Method for Multi-Fluid Flows [PDF]
, 2011 This paper presents the Particle Finite Element Method (PFEM) and its application to multi-fluid flows. Key features of the method are the use of a Lagrangian description to model the motion of the fluid particles (nodes) and that all the information is associated to the particles.

Evaluating the performance of the particle finite element method in parallel architectures [PDF]
Computational Particle Mechanics, 2014 This paper presents a high performance implementation for the particle-mesh based method called particle finite element method two (PFEM-2). It consists of a material derivative based formulation of the equations with a hybrid spatial discretization which uses an Eulerian mesh and Lagrangian particles.
