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 ...

Application of the Coupled Eulerian Lagrangian method to the prediction of single‐grain cutting forces in grinding

Proceedings in Applied Mathematics and Mechanics, Volume 22, Issue 1, March 2023., 2023
Abstract Continuous technological advancements in the field of grinding technology and improved grinding tools have contributed to the development of high performance grinding processes. One example of such a process is internal traverse grinding (ITG) with electroplated cBN grinding wheels, where the tool consists of a conical roughing zone and a ...

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

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.

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

Mathematical 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.

Enhanced cone penetration test interpretation with the Particle Finite Element Method (PFEM)

, 2019
The paper presents an enhanced interpretation of the cone penetration test based on numerical analysis performed using the Particle Finite Element Method (PFEM). This method allows the incorporation of strong non-linearities, notably those associated with the large displacements and strains arising from the process of the penetration of the cone ...

Investigation of Solution Accuracy in PFEM Simulations Using Benchmark Problems

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT The simulation of large topological changes, such as those occurring in Cone Penetration Testing (CPT) and vibratory pile driving, remains a major challenge in computational geomechanics. Excessive mesh distortions render classical approaches like the Finite Element Method (FEM) unsuitable, emphasizing the need for alternative methodologies ...
