Fracture propagation using the radial point interpolation method

Fatigue & Fracture of Engineering Materials & Structures, 2019
AbstractThis work presents a crack path prediction algorithm combined with the radial point interpolation method (RPIM), a meshless method. To allow easier implementation in existing structural analysis software, this algorithm is numerically compatible with finite element method (FEM) formulations.

Pseudospectral Meshless Radial Point Hermit Interpolation Versus Pseudospectral Meshless Radial Point Interpolation

International Journal of Computational Methods, 2019
This paper develops pseudospectral meshless radial point Hermit interpolation (PSMRPHI) and pseudospectral meshless radial point interpolation (PSMRPI) in order to apply to the elliptic partial differential equations (PDEs) held on irregular domains subject to impedance (convective) boundary conditions.

A Stochastic Radial Point Interpolation Method for Wideband Uncertainty Analysis

IEEE Antennas and Wireless Propagation Letters, 2021
In this letter, a time-domain stochastic radial point interpolation method (SRPIM) is developed for uncertainty quantification of electromagnetic systems. Derivatives of field quantities in Maxwell’s equations are obtained using radial basis function, and stochasticity in the dielectric constant of a part of the model space is incorporated into this ...

The local radial point interpolation meshless method for solving Maxwell equations

Engineering with Computers, 2017
The Maxwell equations are basic equations of electromagnetic. In this paper we employed ADI–LRPIM (alternative direction implicit method is applied for approximating the time variable and the local radial point interpolation meshless method is used for space variable) to solve the two-dimensional time dependent Maxwell equations.

First- and second-order meshless radial point interpolation methods in electromagnetics

2014 1st Australian Microwave Symposium (AMS), 2014
This paper compares two different approaches for the time-domain meshless Radial Point Interpolation Method (RPIM) in electromagnetic simulations. These two algorithms are classified based on the order of partial differential equations which are needed for solving EM problems.

A LINEARLY CONFORMING RADIAL POINT INTERPOLATION METHOD FOR SOLID MECHANICS PROBLEMS

International Journal of Computational Methods, 2006
A linearly conforming radial point interpolation method (LC-RPIM) is presented for stress analysis of two-dimensional solids. In the LC-RPIM method, each field node is enclosed by a Voronoi polygon, and the displacement field function is approximated using RPIM shape functions of Kronecker delta function property created by simple interpolation using ...
