Adaptive procedures for meshfree RBF unsymmetric and symmetric collocation methods
Applied Mathematics and Computation, 2020 In this article we present an adaptive scheme for solving radial basis function collocation problems, which involve elliptic partial differential equations. The proposed algorithm is applied to two usual numerical methods, known as the nonsymmetric Kansa’

Conforming window functions for meshfree methods
Computer Methods in Applied Mechanics and Engineering, 2019 Window functions provide a base for the construction of approximation functions in many meshfree methods. They control the smoothness and extent of the approximation functions and are commonly defined using Euclidean distances which helps eliminate the ...

Numerical simulation of dry laser derusting process based on SPH method
AIP Advances, 2023 Laser cleaning is an efficient, environmental-friendly, and non-contact surface treatment technology. Laser radiation and heating cause the surface material to heat up and gasify, separating it from the substrate. Traditional mesh-based numerical methods

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 ...

A nodal integration scheme for meshfree Galerkin methods using the virtual element decomposition [PDF]
International Journal for Numerical Methods in Engineering, 2019 In this article, we present a novel nodal integration scheme for meshfree Galerkin methods, which draws on the mathematical framework of the virtual element method. We adopt linear maximum‐entropy basis functions for the discretization of field variables,
