An Enriched Radial Point Interpolation Method (e-RPIM) for the Analysis of Crack Tip

AIP Conference Proceedings, 2010
In this paper, an enriched radial point interpolation method (e‐RPIM) is developed for the determination of crack tip fields. The conventional RBF interpolation is novelly augmented by the suitable trigonometric basis functions to reflect the properties of stresses for the crack tip fields.

A Novel Virtual Node Selection Scheme of Cell-Based Smoothed Radial Point Interpolation Method (CS-RPIM) for Mid-Frequency Acoustic Problems

International Journal of Computational Methods, 2022
Due to the “overly-stiff” nature, it has been proved that the finite element method (FEM) is inevitable to suffer from the dispersion error when solving mid-frequency acoustic problems. In order to overcome this defect, in this study, a novel virtual node selection scheme of changing the virtual node’s position with a parameter is proposed, which is ...

Simulation of activator–inhibitor dynamics based on cross-diffusion Brusselator reaction–diffusion system via a differential quadrature-radial point interpolation method (DQ-RPIM) technique

The European Physical Journal Plus, 2021
The current paper proposes an efficient numerical procedure for solving the two-dimensional Brusselator reaction–diffusion system. First, the time derivative is discretized by a semi-implicit finite difference scheme such that the nonlinear terms are approximated by using one term of the Taylor expansion.

Numerical analysis for multi-group neutron-diffusion equation using Radial Point Interpolation Method (RPIM)

Annals of Nuclear Energy, 2017
Abstract A mesh-free method is introduced to overcome the drawbacks (e.g., mesh generation and connectivity definition between the meshes) of mesh-based (nodal) methods such as the finite-element method and finite-difference method. In particular, the Point Interpolation Method (PIM) using a radial basis function is employed in the numerical analysis

The radial point interpolation method (RPIM) for analyzing a V-shaped electrothermal actuator

Journal of Micromechanics and Microengineering
Abstract Electrothermally actuated micro-beams are expected to be massively adopted in the micromanipulation and microassembly, due to their easy access to a larger motion. As a case study in this work, an amended electrothermal analytical submodel governing the temperature distribution of the V-shaped actuator is first established ...

MESHFREE CELL-BASED SMOOTHED ALPHA RADIAL POINT INTERPOLATION METHOD (CS-α RPIM) FOR SOLID MECHANICS PROBLEMS

International Journal of Computational Methods, 2013
This paper presents a novel and effective cell-based smoothed alpha radial point interpolation method (CS-αRPIM) using αPIM shape functions for approximating displacement and cell-based smoothed strains for displacement gradient construction. Using a scaling factor α ∈ [0, 1], the αPIM shape functions are combinations of the condensed RPIM (RPIM-Cd ...
