A Study of the Partition of Unity-based T3-CNS and T3-DNS Finite Elements in Surface Fitting

open access: yesCivil Engineering Dimension
Various alternative, enhanced finite element methods (FEMs) have been proposed to improve the accuracy and convergence of traditional FEM. One promising approach is the hybrid FEM-meshfree method using the partition of unity concept. This study examines

Evaluation of coupled finite element/meshfree method for a robust full-scale crashworthiness simulation of railway vehicles

open access: yesAdvances in Mechanical Engineering, 2016
The crashworthiness of a railway vehicle relates to its passive safety performance. Due to mesh distortion and difficulty in controlling the hourglass energy, conventional finite element methods face great challenges in crashworthiness simulation of ...

Recent Progress on Mesh-free Particle Methods for Simulations of Multi-phase Flows: A Review

open access: yesKONA Powder and Particle Journal, 2019
The discrete element method (DEM) and the moving particle semi-implicit (MPS) method are the most popular mesh-free particle methods in the discontinuum and continuum. This paper describes a state-of-the-art modeling on multi-phase flows using these mesh-

A quasi-RBF technique for numerical discretization of PDE's [PDF]

open access: yes, 2002
Atkinson developed a strategy which splits solution of a PDE system into homogeneous and particular solutions, where the former have to satisfy the boundary and governing equation, while the latter only need to satisfy the governing equation without ...
