The surface‐reconstruction virtual‐region mesh update method for problems with topology changes
International Journal for Numerical Methods in Engineering, Volume 124, Issue 9, Page 2050-2067, 15 May 2023., 2023 Abstract In this work, we introduce a novel boundary‐conforming mesh‐update method that is particularly designed for problems with large boundary displacements and topology changes. This method, which we call the surface‐reconstruction virtual‐region mesh update method, integrates the virtual region approach and a surface reconstruction process to ...

International 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 ...

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