A node-based smoothed conforming point interpolation method (NS-CPIM) for elasticity problems [PDF]

open access: yes, 2011
This paper formulates a node-based smoothed conforming point interpolation method (NS-CPIM) for solid mechanics. In the proposed NS-CPIM, the higher order conforming PIM shape functions (CPIM) have been constructed to produce a continuous and piecewise ...

Optimization of Friction Stir Weld Joint Quality Using a Meshfree Fully-Coupled Thermo-Mechanics Approach

open access: yesMetals, 2018
There is currently a need for an efficient numerical optimization strategy for the quality of friction stir welded (FSW) joints. However, due to the computational complexity of the multi-physics problem, process parameter optimization has been a goal ...

On the infinite particle limit in Lagrangian dynamics and convergence of optimal transportation meshfree methods [PDF]

open access: yes, 2013
We consider Lagrangian systems in the limit of infinitely many particles. It is shown that the corresponding discrete action functionals Gamma-converge to a continuum action functional acting on probability measures of particle trajectories.

NURBS-Enhanced Meshfree Method with an Integration Subtraction Technique for Complex Topology

open access: yesApplied Sciences, 2020
In this paper, we present an integration subtraction technique to model holes interactively in a predesigned domain for adaptive problems. This technique involves two approaches, the normal subtraction technique and the moving subtraction technique.

Meshfree particle method [PDF]

open access: yesProceedings Ninth IEEE International Conference on Computer Vision, 2003
Many of the computer vision algorithms have been posed in various forms of differential equations, derived from minimization of specific energy functionals, and the finite element representation and computation have become the de facto numerical strategies for solving these problems. However, for cases where domain mappings between numerical iterations

Phase-field modeling and simulation of fracture in brittle materials with strongly anisotropic surface energy [PDF]

open access: yes, 2015
Crack propagation in brittle materials with anisotropic surface energy is important in applications involving single crystals, extruded polymers, or geological and organic materials. Furthermore, when this anisotropy is strong, the phenomenology of crack
