THE PARTICLE FINITE ELEMENT METHOD — AN OVERVIEW

open access: yesInternational Journal of Computational Methods, 2004
We present a general formulation for the analysis of fluid-structure interaction problems using the particle finite element method (PFEM). The key feature of the PFEM is the use of a Lagrangian description to model the motion of nodes (particles) in both the fluid and the structure domains.

Discrete element method to simulate continuous material by using the cohesive beam model [PDF]

open access: yes, 2012
The mechanical behavior of materials is usually simulated by the continuous mechanics approach. However, simulation of non-continuous phenomena like multi fracturing is not well adapted to a continuous description.

A Lagrangian–Eulerian procedure for the coupled solution of the Navier–Stokes and shallow water equations for landslide-generated waves

open access: yesAdvanced Modeling and Simulation in Engineering Sciences, 2022
This work presents a partitioned method for landslide-generated wave events. The proposed strategy combines a Lagrangian Navier Stokes multi-fluid solver with an Eulerian method based on the Boussinesq shallow water equations.

A multi-scale coupling finite element method based on the microscopic of soil particle motions

open access: yesRock and Soil Mechanics, 2021
Soil is a multi-phase and multi-scale geomaterial that exhibits dramatically inhomogeneous and discontinuous physical nature. Conventional finite element method, which is conceptualized at a single macroscale and ignores the control mechanism of soil at ...

A State of the Art Review of the Particle Finite Element Method (PFEM) [PDF]

open access: yesArchives of Computational Methods in Engineering, 2020
AbstractThe particle finite element method (PFEM) is a powerful and robust numerical tool for the simulation of multi-physics problems in evolving domains. The PFEM exploits the Lagrangian framework to automatically identify and follow interfaces between different materials (e.g. fluid–fluid, fluid–solid or free surfaces).

Swarm Intelligent Optimization Conjunction with Kriging Model for Bridge Structure Finite Element Model Updating

open access: yesBuildings, 2022
For the simple bridge structure, the finite element model established by drawing and elastic mechanics method is accurate. However, when faced with large and complex long-span bridge structures, there are inevitable differences between the finite element
