Analysis of the Element-Free Galerkin Method with Penalty for Stokes Problems [PDF]
Entropy, 2022 The element-free Galerkin (EFG) method with penalty for Stokes problems is proposed and analyzed in this work. A priori error estimates of the penalty method, which is used to deal with Dirichlet boundary conditions, are derived to illustrate its ...

Evaluation of coupled finite element/meshfree method for a robust full-scale crashworthiness simulation of railway vehicles [PDF]
Advances in Mechanical Engineering, 2016 The crashworthiness of a railway vehicle relates to its passive safety performance. Due to mesh distortion and difficulty in controlling the hourglass energy, conventional finite element methods face great challenges in crashworthiness simulation of ...

On Interpolative Meshless Analysis of Orthotropic Elasticity
Buildings, 2023 As one possible alternative to the finite element method, the interpolation characteristic is a key property that meshless shape functions aspire to. Meanwhile, the interpolation meshless method can directly impose essential boundary conditions, which is

Locking in the incompressible limit for the element‐free Galerkin method [PDF]
International Journal for Numerical Methods in Engineering, 2001 AbstractVolumetric locking (locking in the incompressible limit) for linear elastic isotropic materials is studied in the context of the element‐free Galerkin method. The modal analysis developed here shows that the number of non‐physical locking modes is independent of the dilation parameter (support of the interpolation functions).
