Meshless Galerkin method based on RBFs and reproducing Kernel for quasi-linear parabolic equations with dirichlet boundary conditions

Mathematical Modelling and Analysis, 2021
The main aim of this paper is to present a hybrid scheme of both meshless Galerkin and reproducing kernel Hilbert space methods. The Galerkin meshless method is a powerful tool for solving a large class of multi-dimension problems.

An improved meshless method for finite deformation problem in compressible hyperelastic media

Vietnam Journal of Mechanics, 2021
Hyperelastic materials are considered as special category of elastic solid materials because of their nonlinear complicated constitutive laws. Due to large strain state, the behaviour of such materials is often considered in finite deformation analysis.

Strength prediction of a single lap joint under impact using meshless methods

Composites Part C: Open Access, 2023
The use of adhesive joints in structures subjected to dynamic loads, such as wind turbines and cars, makes it important to study them under those conditions. Numerical models are an integral part of that. Commonly the Finite Element Method (FEM) is used,

Moving-boundary problems solved by adaptive radial basis functions [PDF]

, 2010
The objective of this paper is to present an alternative approach to the conventional level set methods for solving two-dimensional moving-boundary problems known as the passive transport. Moving boundaries are associated with time-dependent problems and
