Numerical solution for one-dimensional pure-convection problems using the high-order Taylor-Galerkin element-free method [PDF]

مهندسی عمران شریف
The present study proposes a novel approach for solving one-dimensional pure convection problems, utilizing a high-order Taylor Galerkin element-free method. The standard Galerkin method has limitations in solving such problems due to the predominance of

Application of Moving Kriging Shape Functions on Plate Problems

NUST Journal of Engineering Sciences, 2008
The Moving Kriging (MK) interpolation was recently proposed as a superior substitution of the Moving Least Square (MLS) approximation in the construction of shape functions for the Element-Free Galerkin Method (EFGM).

Coupling of FEM and EFGM with dynamic decomposition in 2D quasi-brittle crack growth analysis

Computer Assisted Methods in Engineering and Science, 2023
In the paper three computational models for crack growth analysis in quasi-brittle materials in plane stress state are presented. These models have been worked out on the base of different methods of coupling the finite element method and the element ...

Assessment of mesh orientation, Arbitrary‐Lagrangian‐Eulerian remeshing and mass scaling in 3D finite‐element modeling of thread‐forming screw connections Bewertung der Netzausrichtung, Arbitrary‐Lagrangian‐Eulerian‐Neuvernetzung und Massenskalierung bei der 3D‐Finite‐Elemente‐Modellierung von gewindefurchenden Schraubverbindungen

Materialwissenschaft und Werkstofftechnik, EarlyView.
An approach to quantify the mesh quality for simulations of bolted joints with formed female threads has been conducted for different meshing strategies. Depending on mesh orientation, Arbitrary‐Lagrangian‐Eulerian remeshing and mass scaling the quotient qH was evaluated.

Modeling n‐Butyl Acrylate Polymerization using Complementary Modeling Techniques

Macromolecular Reaction Engineering, EarlyView.
Two different simulation methods are used for the radical polymerization of nBA: deterministic in Predici and stochastic with mcPolymer. It has been successfully implemented across a wide temperature range. It turns out that the partially different implementation of chain‐length‐dependent termination and β‐scission are important for obtaining ...

Vibration Attenuation of Cantilever Beam Using Electromagnetic Delayed Feedback

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study presents a combined analytical and numerical investigation of a single‐input single‐output delayed feedback controller designed to suppress vibrations in a cantilever beam actuated by an electromagnet positioned beneath its free end. An analytical model was developed using the linearized equation of motion for a transversely excited

A Modification of the Moving Least-Squares Approximation in the Element-Free Galerkin Method

Journal of Applied Mathematics, 2014
The element-free Galerkin (EFG) method is one of the widely used meshfree methods for solving partial differential equations. In the EFG method, shape functions are derived from a moving least-squares (MLS) approximation, which involves the inversion of ...

A Geometrically Regularized Gradient‐Damage Model With Orthogonality‐Based Energy Split for Dynamic Anisotropic Compression‐Shear Fracture

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This study proposes a novel geometrically regularized gradient‐damage model for simulating dynamic mixed‐mode fracture in orthotropic materials with tension–compression asymmetry. In this model, a thermodynamic framework is formulated by incorporating damage dissipation into internal energy evolution, from which the constitutive relation and ...
