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.

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.

A study of compaction of composite particles by multi-particle finite element method
Composites Science and Technology, 2009We 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.

A Finite Element Particle Method for Extreme Deformation Problems
International Journal for Numerical Methods in EngineeringABSTRACT A novel finite element particle method (FEPM) is proposed in this paper for modeling extreme deformation problems. In a material domain, regions undergoing small deformation are discretized using elements of the finite element method (FEM), while zones subject to extreme deformation are represented with particles of the ...
