Melting and spread of polymers in fire with the particle finite element method

open access: yesInternational Journal for Numerical Methods in Engineering, 2009
AbstractA new computational procedure for analysis of the melting and flame spread of polymers under fire conditions is presented. The method, termed particle finite element method (PFEM), combines concepts from particle‐based techniques with those of the standard finite element method (FEM).

Hybrid finite element and Brownian dynamics method for charged particles [PDF]

open access: yesThe Journal of Chemical Physics, 2016
Diffusion is often the rate-determining step in many biological processes. Currently, the two main computational methods for studying diffusion are stochastic methods, such as Brownian dynamics, and continuum methods, such as the finite element method. A previous study introduced a new hybrid diffusion method that couples the strengths of each of these

A Coupled Discrete-Finite Element Method for Shear Strength Analysis of Geogrid-Reinforced Railway Ballast

open access: yesAdvances in Materials Science and Engineering, 2021
This paper presents a coupled discrete-finite element method for the investigation of shear strength of geogrid-reinforced ballast by direct shear tests and pull-out tests. The discrete element method (DEM) and finite element method (FEM) are employed to

A Smooth Partition of Unity Finite Element Method for Vortex Particle Regularization [PDF]

open access: yesSIAM Journal on Scientific Computing, 2017
We present a new class of $C^\infty$-smooth finite element spaces on Cartesian grids, based on a partition of unity approach. We use these spaces to construct smooth approximations of particle fields, i.e., finite sums of weighted Dirac deltas. In order to use the spaces on general domains, we propose a fictitious domain formulation, together with a ...

Fast quasi-implicit NOSB peridynamic simulation based on FIRE algorithm

open access: yesMechanical 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.

Optimization of riveting parameters using Kriging and particle swarm optimization to improve deformation homogeneity in aircraft assembly

open access: yesAdvances in Mechanical Engineering, 2017
Riveting parameters have significant effects on the material growth/material expansion and quality of a joint. However, the inhomogeneity of material growth leads to assembly deformation and degrades the dimensional accuracy of the final products.
