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.

Cut-PFEM: a Particle Finite Element Method using unfitted boundary meshes [PDF]
Engineering With ComputersAbstractIn this work, we present a novel unfitted mesh boundary strategy in the context of the Particle Finite Flement Method (PFEM) aiming to improve endemic limitations of the PFEM relative to boundary conditions treatment and mass conservation. In this new methodology, which we called Cut-PFEM, the fluid–wall interaction is not performed by adding ...

High Heat Resistance Can Be Deceiving: Dripping Behavior of Polyamide 4.6 in Fire
Macromolecular Materials and Engineering, 2023 Polyamide 4.6 (PA46) is a high‐heat‐resistant polymer, but it has no dripping resistance under fire. Three commercial grades of PA46 are investigated under UL 94 vertical fire test conditions.

Numerical simulation of undrained insertion problems in geotechnical engineering with the Particle Finite Element Method (PFEM) [PDF]
Computers and Geotechnics, 2017 The paper presents total-stress numerical analyses of large-displacement soil-structure interaction problems in geomechanics using the Particle Finite Element Method (PFEM). This method is characterized by frequent remeshing and the use of low order finite elements to evaluate the solution.

Analysis of fluid-soil-structure interaction problems with the Particle Finite Element Method (PFEM) [PDF]
, 2012 We present some developments in the Particle Finite Element Method (PFEM) for analysis of coupled problems in mechanics involving fluid-soil-structure interaction (FSSI). The PFEM uses an updated Lagrangian description to model the motion of material points in both the fluid and the solid domains (the later including soil/rocks and structures).
