Free Vibration Analysis of Bulkhead-Stiffened Functionally Graded Open Shell Using a Meshless Method

open access: yesShock and Vibration, 2022
This paper focuses on the free vibration analysis of bulkhead-stiffened functionally graded open shell (FGOS) by means of the first-order shear deformation theory (FSDT) and the meshless strong form method.

Meshless methods: theory and application in 3D fracture modelling with level sets [PDF]

open access: yes, 2010
Accurate analysis of fracture is of vital importance yet methods for effetive 3D calculations are currently unsatisfactory. In this thesis, novel numerical techniques are developed which solve many of these problems. This thesis consists two major parts:

Analysis of microelectromechanical systems (MEMS) devices by the meshless point weighted least-squares method

open access: yes, 2007
In this paper, the characteristics of microelectromechanical systems (MEMS) devices are analyzed by a meshless method—point weighted least-squares (PWLS) method. In the present meshless method, field nodes and collocation points are adopted.

On the Numerical Solution of the Poisson Equation in the Smoothed Particle Hydrodynamics

open access: yesStudies in Applied Mathematics, Volume 157, Issue 4, October 2026.
ABSTRACT In the present work, we address some aspects related to the numerical solution of the Poisson equation within the framework of the Smoothed Particle Hydrodynamics (SPH). In this case, the Poisson equation is solved using nonlocal, kernel‐based discretizations of the differential operators (i.e., gradient, divergence, and Laplacian operators ...

A novel meshless approach – Local Kriging (LoKriging) method with two-dimensional structural analysis

open access: yes, 2003
This paper develops a novel meshless approach, called Local Kriging (LoKriging) method, which is based on the local weak form of the partial differential governing equations and employs the Kriging interpolation to construct the meshless shape functions.

Maximum‐Entropy‐Based Meshless Modeling of Surface‐Tension‐Driven Large Deformation

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 17, 15 September 2026.
ABSTRACT Soft material modeling is challenging due, among others, to the substantial structural changes these materials undergo. In this context, meshless methods offer a promising alternative to overcome the limitations of established mesh‐based approximations such as finite elements. However, they introduce new challenges.

A Meshless Method for Analysis of 3D Medical Parts

open access: yesMATEC Web of Conferences, 2016
A proposed method based on a so-called meshless method is designed to simulate the structural behaviors of 3D medical parts. To do the simulation, the STL (Stereo-Lithography) geometry, which is the main geometry format used in 3D printing and medical ...

A review of numerical methods for flow and transport modeling in the vadose zone

open access: yesVadose Zone Journal, Volume 25, Issue 5, September/October 2026.
Abstract Accurate modeling of subsurface flow and transport processes in the vadose zone, governed by the Richards equation and advection‐dispersion equation, respectively, poses major numerical challenges due to the strong nonlinearity of the governing partial differential equations, spatial heterogeneity and anisotropy of the media parameters, and ...

A Novel Optimized Local Linearization Hybrid Block Method for Chaotic Systems: Applications to Stretch‐Twist‐Fold Flow and Bond Orbital Chaotic Attractors

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 12, Page 13148-13175, August 2026.
ABSTRACT The numerical approximation of nonlinear chaotic differential systems, such as the modified stretch‐twist‐fold (STF) flow and multi‐bond chaotic attractors, presents a significant challenge due to their sensitive dependence on initial conditions and complex dynamics where analytical solutions are unattainable.
