Exact Dirichlet boundary multi‐resolution hash encoding solver for structures
Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 25, Page 4172-4192, 20 October 2025.Abstract Designed to address computationally expensive scientific problems, physics‐informed neural networks (PINNs) have primarily focused on solving issues involving relatively simple geometric shapes. Drawing inspiration from exact Dirichlet boundary PINN and neural representation field, this study first develops a multi‐resolution hash encoding ...

International Journal of Mechanical System Dynamics, Volume 5, Issue 1, Page 40-66, March 2025.ABSTRACT This research article introduces a high‐order finite element model based on the first‐order shear deformation theory to analyze the hygrothermal static responses of nanoscale, multidirectional nanofunctionally graded piezoelectric (NFGP) plates resting on variable elastic foundations. The study considers the material properties of these plates,

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 ...

Meshless Local Petrov-Galerkin Method for Plane Piezoelectricity
Computers, Materials & Continua, 2006 Piezoelectric materials have wide range engineering applications in smart structures and devices. They have usually anisotropic properties. Except this complication electric and mechanical fields are coupled each other and the governing equations are much more complex than that in the classical elasticity. Thus, efficient computational methods to solve
