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 ...

An ellipsoidal particle–finite element method for hypervelocity impact simulation [PDF]
International Journal for Numerical Methods in Engineering, 2003 AbstractA number of coupled particle–element and hybrid particle–element methods have been developed for the simulation of hypervelocity impact problems to avoid certain disadvantages associated with the use of pure continuum‐based or pure particle‐based methods. To date these methods have employed spherical particles.

Bonding mechanism from the impact of thermally sprayed solid particles [PDF]
, 2009 Power particles are mainly in solid state prior to impact on substrates from high velocity oxy-fuel (HVOF) thermal spraying. The bonding between particles and substrates is critical to ensure the quality of coating.

Enrichment of the Finite Element Method With the Reproducing Kernel Particle Method [PDF]
Journal of Applied Mechanics, 1997 The reproducing kernel particle method (RKPM) has attractive properties in handling high gradients, concentrated forces, and large deformations where other widely implemented methodologies fail. In the present work, a multiple field computational procedure is devised to enrich the finite element method with RKPM, and RKPM with analytical functions. The

Fast quasi-implicit NOSB peridynamic simulation based on FIRE algorithm
Mechanical Engineering Journal, 2019 The peridynamics is a particle methods considered superior to the finite element method in describing fracture phenomena since fracture can be simply expressed as bond breaking between the peridynamics particles.

A Semi-Lagrangian Particle Level Set Finite Element Method for Interface Problems [PDF]
, 2013 We present a quasi-monotone semi-Lagrangian particle level set (QMSL-PLS) method for moving interfaces. The QMSL method is a blend of first order monotone and second order semi-Lagrangian methods.
