A nodal-integration based particle finite element method (N-PFEM) to model cliff recession
Geomorphology, 2021 Cliff recession poses a significant threat to the built environment, transportation infrastructure and land use. In this paper, a novel computational framework called the Nodal-integration based Particle Finite Element Method (N-PFEM) is developed for ...

Cut-PFEM: a Particle Finite Element Method using unfitted boundary meshes
Engineering With ComputersIn 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.

Sediment transport problems by the particle finite element method (PFEM)
Computational Particle Mechanics, 2020 This paper presents a particle finite element model for the numerical simulation of sediment transport problems. Fluid motion and sediment motion are coupled in a two-way manner, through boundary shear stress field and through flow domain mesh ...

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.

Journal of Rock Mechanics and Geotechnical Engineering, 2023 In this paper, the application of Abaqus-based particle finite element method (PFEM) is extended from static to dynamic large deformation. The PFEM is based on periodic mesh regeneration with Delaunay triangulation to avoid mesh distortion.

Using the particle finite element method for predicting edge-cracking in complex phase high-strength steel sheets [PDF]
MATEC Web of ConferencesAdvanced High-strength steel (AHSS) sheets enable lightweight designs by reducing material thickness while retaining necessary structural properties. However, their high strength often complicates forming operations and increases vulnerability to defects
