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.

Modeling Grinding Processes—Mesh or Mesh-Free Methods, 2D or 3D Approach?
Journal of Manufacturing and Materials Processing, 2022 The objectives of this study are mainly two: (1) to validate whether a single grain scratch process can be modeled in two dimensions under the assumption of plane strain, and (2) to select the best discretization approach to model a single grain scratch ...

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.
