Prediction of Chloride Diffusion in Concrete Structure Using Meshless Methods [PDF]

open access: yesAdvances in Materials Science and Engineering, 2016
Degradation of RC structures due to chloride penetration followed by reinforcement corrosion is a serious problem in civil engineering. The numerical simulation methods at present mainly involve finite element methods (FEM), which are based on mesh ...

Unsymmetric meshless methods for operator equations [PDF]

open access: yesNumerische Mathematik, 2009
The author proposes a general approach for approximatively solving the well-posed linear operator equations in normed linear spaces. The operators need not be elliptic and the problems can be posed in weak or strong form without changing the theory. The paper seems to be the first to provide a rigid mathematical foundation of certain variations of the `

Localized boundary-domain integral formulations for problems with variable coefficients [PDF]

open access: yes, 2002
Specially constructed localized parametrixes are used in this paper instead of a fundamental solution to reduce a boundary value problem with variable coefficients to a localized boundary-domain integral or integro-differential equation (LBDIE or LBDIDE).

Adaptive meshless centres and RBF stencils for Poisson equation [PDF]

open access: yes, 2011
We consider adaptive meshless discretisation of the Dirichlet problem for Poisson equation based on numerical differentiation stencils obtained with the help of radial basis functions. New meshless stencil selection and adaptive refinement algorithms are

Approximation of partial integro differential equations with a weakly singular kernel using local meshless method

open access: yesAlexandria Engineering Journal, 2020
In this work, a meshless method in local setting and Laplace transform are coupled to approximate partial integro-differential equations (PIDEs). The typical method of obtaining the approximate solution of such type of equations is to use the meshless ...

An adaptive meshless method of line based on radial basis functions [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2015
In this paper, an adaptive meshless method of line is applied to distribute the nodes in the spatial domain. In many cases in meshless methods, it is also necessary for the chosen nodes to have certain smoothness properties.
