Two‐phase model for the excavation analysis in partially saturated soft soils using the particle finite element method

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 47, Issue 2, Page 145-186, 10 February 2023., 2023
Abstract A two‐phase velocity‐pressure stabilized formulation is proposed for the numerical analysis of mechanized excavations in partially saturated soft soils using the Particle Finite Element Method (PFEM). The fully coupled formulation is based on the theory of porous media in association with the Soil Water Characteristic Curve and the porosity ...

High‐performance computing of 3D blasting wave propagation in underground rock cavern by using 4D‐LSM on TianHe‐3 prototype E class supercomputer

open access: yesDeep Underground Science and Engineering, Volume 1, Issue 1, Page 87-100, September 2022., 2022
The blasting wave propagation simulated by the parallel computing of four‐dimensional lattice spring model (4D‐LSM). The attenuation of stress wave, the reflection on fixed boundary and the subsequent stress wave after the duration of blasting loading are reproduced.

3D Numerical Simulation of Landslides for the Full High Waste Dump Using SPH Method

open access: yesAdvances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021
Waste dump that is generally composed of a large number of loose geotechnical materials is prone to landslides under external loads. In this work, the smoothed particle hydrodynamics (SPH) method combined with the Mohr–Coulomb model is used to study the dynamic characteristics of the landslides that occurred in the waste dump during the failure process.

Using the particle finite element method for predicting edge-cracking in complex phase high-strength steel sheets [PDF]

open access: yesMATEC Web of Conferences
Advanced High-strength steel (AHSS) sheets enable lightweight designs by reducing material thickness while retaining necessary structural properties. However, their high strength often complicates forming operations and increases vulnerability to defects

A nodal-integration based particle finite element method (N-PFEM) to model cliff recession

open access: yesGeomorphology, 2021
Abstract Cliff recession poses a significant threat to the built environment, transportation infrastructure and land use. In this paper, a novel computational framework called the Nodal-integration based Particle Finite Element Method (N-PFEM) is developed for modelling the cliff recession resulting from weathering-induced landslides.

Interaction between an elastic structure and free-surface flows: experimental versus numerical comparisons using the PFEM. [PDF]

open access: yes, 2008
The paper aims to introduce new fluid–structure interaction (FSI) tests to compare experimental results with numerical ones. The examples have been chosen for a particular case for which experimental results are not much reported. This is the case of FSI

An explicit Lagrangian finite element method for free-surface weakly compressible flows [PDF]

open access: yes, 2016
In the present work, an explicit finite element approach to the solution of the Lagrangian formulation of the Navier-Stokes equations for weakly compressible fluids or fluid-like materials is investigated.

Validation of the particle finite element method (PFEM) for simulation of free surface flows [PDF]

open access: yesEngineering Computations, 2008
PurposeThe purpose of this paper is to evaluate the possibilities of the particle finite element method for simulation of free surface flows.Design/methodology/approachA numerical simulation of a number of examples for which experimental data are available is performed. The simulations are run using the same scale as the experiment in order to minimize
