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.

Prediction of Service Life in Concrete Structures based on Diffusion Model in a Marine Environment Using Mesh Free, FEM and FDM Approaches [PDF]

Journal of Rehabilitation in Civil Engineering, 2020
Chloride-induced corrosion is a key factor in the premature corrosion of concrete structures exposed to a marine environment. Fick's second law of diffusion is the dominant equation to model diffusion of chloride ions.

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 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 ...

Analyzing Three-Dimensional Laplace Equations Using the Dimension Coupling Method

Mathematics, 2023
Due to the low computational efficiency of the Improved Element-Free Galerkin (IEFG) method, efficiently solving three-dimensional (3D) Laplace problems using meshless methods has been a longstanding research direction.

Volume Quantization with Flexible Singularities for Hexahedral Meshing

Computer Graphics Forum, EarlyView.
Abstract We present a novel algorithm for quantization and subsequent hexahedral mesh generation from seamless volumetric maps. Quantization is the process of choosing integers that represent the numbers of hexahedral elements to be placed in each region of the volume, and transforming the seamless map into an integer‐grid map matching that choice ...

Overcoming Computational Bottlenecks in Quantum Hydrodynamics: A Volume‐Based Integral Formalism for Spherical Nanoparticles

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
Numerical modeling of mesoscopic material response models that capture the quantum dynamics of electrons does not have to come with discouraging computational bottlenecks. The main message is that through a shift in perspective in modeling toward integral equation methods and exploiting symmetry‐based arguments, it is possible to capture complicated ...

Sensitivity of Double‐Diffusive Mixed Convection in an Enclosure With a Zigzag Bottom Wall and a Torsionally Oscillating Lid Using Hybrid Nanofluid

Engineering Reports, Volume 8, Issue 7, July 2026.
This study investigates the nature of sensitivity of an unsteady double‐diffusive mixed convective analysis in a trapezoidal enclosure featuring a zigzag bottom wall and a torsionally oscillating lid. This cavity is filled by a hybrid nanofluid (Ag‐MgO‐H2O). The cavity also contains internal heat generation.
