C–PINN: A Coupled Physics‐Informed Neural Network for Solving Parabolic Two‐Step Models in Electron–Lattice Thermal Conduction

International Journal of Mathematics and Mathematical Sciences, Volume 2025, Issue 1, 2025.
This paper introduces a coupled physics‐informed neural network (C–PINN) framework for simulating electron–lattice thermal conduction. The framework uses an additive Δ‐decomposition to couple the electron temperature Te and lattice temperature Tl, with a learnable correction term Δ(t, x) capturing spatial–temporal deviations from thermal equilibrium ...

Physics‐informed neural operator solver and super‐resolution for solid mechanics

Computer-Aided Civil and Infrastructure Engineering, Volume 39, Issue 22, Page 3435-3451, 15 November 2024.
Abstract Physics‐Informed Neural Networks (PINNs) have solved numerous mechanics problems by training to minimize the loss functions of governing partial differential equations (PDEs). Despite successful development of PINNs in various systems, computational efficiency and fidelity prediction have remained profound challenges.

The Meshless Local Petrov-Galerkin (MLPG) Method for Solving Incompressible Navier-Stokes Equations [PDF]

, 2001
The truly Meshless Local Petrov-Galerkin (MLPG) method is extended to solve the incompressible Navier-Stokes equations. The local weak form is modified in a very careful way so as to ovecome the so-called Babus~ka-Brezzi conditions.

A meshfree approach for analyzing strain fields near crack tips from Digital Image Correlation displacement data

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 6, Page 1994-2009, June 2024.
Abstract The element‐free Galerkin (EFG) meshfree method is employed in this research to compute strain fields based on discrete displacement data obtained from digital image correlation (DIC). To validate the method's accuracy, both simulated images with highly heterogeneous deformations and real tests conducted on notched specimens with known ...
