Simulation of Cutting processes by the Particle Finite Element Method
GAMM-Mitteilungen, 2017AbstractThe 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, 1986A 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
2006We 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, 2020Particle 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.

A hybrid particle-finite element method for impact dynamics
Nuclear Engineering and Design, 2011Abstract 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

On the Treatment of Plastic Deformation in the Particle Finite Element Method
PAMM, 2018AbstractThe 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].

Coupling of smooth particle hydrodynamics with the finite element method
Nuclear Engineering and Design, 1994Abstract A gridless technique called smooth particle hydrodynamics (SPH) has been coupled with the transient dynamics finite element code pronto . In this paper, a new weighted residual derivation for the SPH method will be presented, and the methods used to embed SPH within pronto will be outlined.

Finite element-particle method calculation of EHD plumes
Annual Report Conference on Electrical Insulation and Dielectric Phenomena, 2003We use the superparticle technique mixed with finite element methods to study the transient and stationary behavior of EHD flows. Calculations show that the technique is suitable to study EHD flows. We have been able to reproduce fairly well the particle distribution and flow pattern for both transient and steady EHD plumes.

Particle Finite Element Methods in Solid Mechanics Problems
2007The paper examines the possibilities of extending the Particle finite element methods (PFEM), which have been successfully applied in fluid mechanics, to solid mechanics problems. After a review of the fundamentals of the method, their specific features in solid mechanics are presented.
