Adaptive Particle Finite Element Method (A‐PFEM) in Metal Cutting Processes [PDF]

PAMM, 2021
AbstractMachining is very common in industry, e.g. automotive industry and aerospace industry, which is a nonlinear dynamic problem including large deformations, large strain, large strain rates and high temperatures, that implies some difficulties for numerical methods such as Finite element method.

A State of the Art Review of the Particle Finite Element Method (PFEM) [PDF]

Archives of Computational Methods in Engineering, 2020
AbstractThe particle finite element method (PFEM) is a powerful and robust numerical tool for the simulation of multi-physics problems in evolving domains. The PFEM exploits the Lagrangian framework to automatically identify and follow interfaces between different materials (e.g. fluid–fluid, fluid–solid or free surfaces).

An implicit locking‐free B‐spline Material Point Method for large strain geotechnical modelling

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 47, Issue 15, Page 2741-2761, 25 October 2023., 2023
Abstract The Material Point Method (MPM) has drawn great attention in the numerical modelling of large deformation, geotechnical problems. The popularity of MPM is mainly because its formulation shares significant similarities with the Finite Element Method.

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 ...
