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 ...

A two-level enriched finite element method for a mixed problem [PDF]
, 2011 The simplest pair of spaces is made inf-sup stable for the mixed form of the Darcy equation. The key ingredient is to enhance the finite element spaces inside a Petrov-Galerkin framework with functions satisfying element-wise local Darcy problems with ...

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 ...

The finite-volume method in computational rheology [PDF]
, 2012 The finite volume method (FVM) is widely used in traditional computational fluid dynamics (CFD), and many commercial CFD codes are based on this technique which is typically less demanding in computational resources than finite element methods (FEM ...

Vehicle-bridge dynamic interaction using finite element modelling [PDF]
, 2010 First investigations on the dynamic response of bridges due to moving loads were motivated by the collapse of the Chester railway bridge in the UK in the middle of the 19th century.

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.

A State of the Art Review of the Particle Finite Element Method (PFEM) [PDF]
Archives of Computational Methods in Engineering, 2020 AbstractThe particle finite element method (PFEM) is a powerful and robust numerical tool for the simulation of multi-physics problems in evolving domains. The PFEM exploits the Lagrangian framework to automatically identify and follow interfaces between different materials (e.g. fluid–fluid, fluid–solid or free surfaces).
