Modeling of Ground Excavation with the Particle Finite-Element Method [PDF]

open access: yesJournal of Engineering Mechanics - ASCE, 2010
The present work introduces a new application of the Particle Finite Element Method (PFEM) for the modeling of excavation problems. PFEM is presented as a very suitable tool for the treatment of excavation problem. The method gives solution for the analysis of all processes that derive from it.

Simulation of Cutting processes by the Particle Finite Element Method

GAMM-Mitteilungen, 2017
AbstractThe cutting process is characterised by large deformations and large configurational changes. Especially the formation of chips and burrs pushes established modeling techniques to their limits. To overcome these difficulties, the particle finite element method (PFEM) combines the benefits of discrete modeling techniques and methods based on ...

Finite Element Method for Charged-Particle Calculations

Nuclear Science and Engineering, 1986
A new method for solving the Boltzmann-Fokker-Planck equation is presented. Following the finite element technique, the solution is projected onto a space defined by linear discontinuous basis functions. Three approaches for the angular flux are derived and compared: the first two for a coupled energy-position discretization and the third one for the ...

Bridging Scale Particle and Finite Element Methods

2006
We summarize the strengths and limitations of currently available multiple-scale techniques, where the emphasis is made on the latest prospective approaches, such as the bridging scale method, multiscale boundary conditions, and multiscale fluidics. Example problems, in which multiple-scale simulation methods yield equivalent results to full atomistic ...

Particle in Cell Finite Element Validation and Verification Methods

2020 IEEE International Symposium on Antennas and Propagation and North American Radio Science Meeting, 2020
Particle in cell codes are used extensively to understand plasma physics and to design devices that exploit these physics. More recent needs (say novel table top accelerators) have given impetus to development of the next generation plasma physics codes that have better fidelity. But despite this need, it is difficult to validate any code.

Moving particle finite element method with global smoothness

International Journal for Numerical Methods in Engineering, 2004
AbstractWe describe a new version of the moving particle finite element method (MPFEM) that provides solutions within a C0 finite element framework. The finite elements determine the weighting for the moving partition of unity. A concept of ‘General Shape Function’ is proposed which extends regular finite element shape functions to a larger domain ...

A hybrid particle-finite element method for impact dynamics

Nuclear Engineering and Design, 2011
Abstract An attachment algorithm for the coupling of smoothed particle hydrodynamics (SPH) and finite element method (FEM) is proposed to take advantage of the best properties of both methods. In the SPH-FEM attachment algorithm, SPH particles are attached to finite element nodes in the coupling interface. Any FE node that is in the support domain of

A study of compaction of composite particles by multi-particle finite element method

Composites Science and Technology, 2009
We study the compaction of composite mixture of soft and hard micro-/nano-size particles using multi-particle finite element method. In this method, each particle is fully discretized into finite element mesh. Local non-uniform contact deformation and non-uniformity stress chains transmitted through the composite are well illustrated.

On the Treatment of Plastic Deformation in the Particle Finite Element Method

PAMM, 2018
AbstractThe particle finite element method (PFEM) combines the benefits of discrete modeling techniques and approaches based on continuum mechanics. It provides a convenient tool to deal with the problem of large configurational change, such as metal cutting, in which nonlinear plasticity plays a key role [1].
