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.

The Finite Element Numerical Investigation of Free Surface Newtonian and Non‐Newtonian Fluid Flows in the Rectangular Tanks

open access: yesMathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
In this paper, we develop a new computational framework to investigate the sloshing free surface flow of Newtonian and non‐Newtonian fluids in the rectangular tanks. We simulate the flow via a two‐phase model and employ the fixed unstructured mesh in the computation to avoid the mesh distortion and reconstruction.
