Advances in the Particle Finite Element Method (PFEM) for Solving Coupled Problems in Engineering

, 2011
We present some developments in the formulation of the Particle Finite Element Method (PFEM) for analysis of complex coupled problems on fluid and solid mechanics in engineering accounting for fluid-structure interaction and coupled thermal effects, material degradation and surface wear.

A hybrid Lagrangian–Eulerian particle finite element method for free‐surface and fluid–structure interaction problems

International Journal for Numerical Methods in Engineering, Volume 125, Issue 5, 15 March 2024.
Abstract The dynamics of fluid flows with free surfaces and interacting with highly deformable structures is a complex problem, attracting considerable attention. The Particle Finite Element Method (PFEM) is one of the various numerical methods recently proposed in the literature to simulate this type of problems. It is a mesh‐based Lagrangian approach,

Numerical analysis of downward progressive landslides in long natural slopes with sensitive clay

Journal of Rock Mechanics and Geotechnical Engineering
Landslides occurring in sensitive clay often result in widespread destruction, posing a significant risk to human lives and property due to the substantial decrease in undrained shear strength during deformation.

A fully explicit fluid-structure interaction approach based on PFEM and FEM [PDF]

, 2017
The numerical simulation of fluid-structure interaction (FSI) problems involving free-surfaces is of great interest in many engineering applications. Particle-based methods, like PFEM, are particularly suited for the analysis of free-surface flows and ...

On the numerical modeling of granular material flows via the Particle Finite Element Method (PFEM)

International Journal of Solids and Structures, 2015
The aim of this work is to describe a numerical framework for reliably and robustly simulating the different kinematic conditions exhibited by granular materials while spreading ---from a stagnant condition, when the material is at rest, to a transition to granular flow, and back to a deposit profile.

Simulation of penetration problems in geomechanics [PDF]

, 2017
The simulation of penetration problems in geomaterials is a challenging problem as it involves large deformations and displacements as well as strong non-linearities affecting material behaviour, geometry and contact surfaces. The paper presents examples
