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

open access: yesComputer-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.

A node-based smoothed conforming point interpolation method (NS-CPIM) for elasticity problems [PDF]

open access: yes, 2011
This paper formulates a node-based smoothed conforming point interpolation method (NS-CPIM) for solid mechanics. In the proposed NS-CPIM, the higher order conforming PIM shape functions (CPIM) have been constructed to produce a continuous and piecewise ...

Meshless Local Petrov-Galerkin Method for Plane Piezoelectricity

open access: yesComputers, 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

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

open access: yesFatigue &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 ...

Assessment of implicit adaptive mesh‐free CFD modelling

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 96, Issue 5, Page 670-700, May 2024.
The paper shows results from an implicit meshless method suitable for the analysis of external aerodynamic flows. This research is using a cloud of points instead of cells, and several stencils are compared for the discretization of the flow equations, along with a least‐squares method.
