Meshless Analysis of Ductile Failure

open access: yesComputer Modeling in Engineering & Sciences, 2008
We study ductile fracture using Reproducing Kernel Particle Interpolation and the Gurson-Tvergaard-Needleman (GTN) model. The meshless simulations are compared with the available experimental results and previous finite element simulations for crack propagation.

Enhancing oil-water flow simulation in shale reservoirs with fractal theory and meshless method

open access: yesFrontiers in Environmental Science, 2023
Introduction: Simulating oil and water flow in shale reservoirs is challenging due to heterogeneity caused by fractures. Conventional grid-based methods often have convergence issues. We propose a new approach using fractal theory and meshless methods to

Error Analysis of Nodal Meshless Methods [PDF]

open access: yes, 2017
There are many application papers that solve elliptic boundary value problems by meshless methods, and they use various forms of generalized stiffness matrices that approximate derivatives of functions from values at scattered nodes $x_1,\ldots,x_M\in Ω\subset\R^d$.
