The Particle Finite Element Method-Second Generation: an overview

, 2016
The main idea of the Particle Finite Element Method in both versions: with moving mesh or with fixed mesh, are to have a set of particles that move in a Lagrangian frame convecting all the physical and mathematical variables (for instance, the density ...

Validation of the particle finite element method (PFEM) for simulation of rock slides in lakes and reservoirs

, 2012
The analysis of landslides in reservoirs is particularly interesting because the oscillation of the water surface elevation (especially rapid drawdowns) can foster their occurrence. The existence of the reservoir for a long enough time makes the material of the slopes turn saturated, thus its pore pressure raises and, as a consequence, its effective ...

SIMSAND Implementation on the Geotechnical Particle Finite Element Method G-PFEM

This paper presents a large-strain implementation of the SIMSAND on the Geotechnical Particle Finite Element Method (G-PFEM). SIMSAND is a simple, critical-state-based constitutive model, which captures the density and pressure dependent behaviour of sands.

Numerical simulation of penetration problems in geotechnical engineering with the particle finite element method (PFEM)

, 2015
This paper highlights a computational framework for the numerical analysis of saturated soil-structure interaction problems. The variational equations of linear momentum and mass balance are obtained for the large deformation case. These equations are solved using the Particle Finite Element Method.
