Reconstruction of implicit surfaces from fluid particles using convolutional neural networks

Computer Graphics Forum, Volume 43, Issue 8, December 2024.
Abstract In this paper, we present a novel network‐based approach for reconstructing signed distance functions from fluid particles. The method uses a weighting kernel to transfer particles to a regular grid, which forms the input to a convolutional neural network.

Modeling cracks in viscoelastic materials at finite strains

International Journal for Numerical Methods in Engineering, Volume 125, Issue 5, 15 March 2024.
Abstract Viscosity is a manifestation of internal friction in materials. Such friction is accompanied by the dissipation of energy, which affects deformation and fracture. In the present work, we develop a new theoretical formulation and its numerical implementation for modeling fracture in viscoelastic soft materials.

A Singularity-Avoiding Moving Least Squares Scheme for Two Dimensional Unstructured Meshes [PDF]

, 2007
Moving least squares interpolation schemes are in widespread use as a tool for numerical analysis on scattered data. In particular, they are often employed when solving partial differential equations on unstructured meshes, which are typically needed ...

Application of the Method of Initial Functions to Study Dynamics and Stress Distribution in Structural Members

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
This study investigates plate analyses employing the method of initial functions (MIFs) across various plate geometries and loading conditions. The conclusions derived from thick rectangular plates highlight substantial thickness‐induced effects on deflection and stress distributions.
