Regularized SPH model for soil–structure interaction with generalized frictional boundary

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 47, Issue 10, Page 1852-1875, July 2023., 2023
Abstract This paper proposes a regularized smoothed particle hydrodynamics (SPH) scheme to solve the problems of tensile instability and stress noise in large‐deformation soil–structure interaction. Particle shifting and stress regularization are combined to maintain uniform stresses and particle distributions.

Modeling Water Flow and Solute Transport in Unsaturated Soils Using Physics‐Informed Neural Networks Trained With Geoelectrical Data

open access: yesWater Resources Research, Volume 59, Issue 6, June 2023., 2023
Abstract Accurate modeling of water flow and solute transport in unsaturated soils is of significant importance for precision agriculture, environmental protection and aquifer management. Traditional modeling approaches are considerably challenging since they require well‐defined boundaries and initial conditions.

Physics‐Informed Neural Networks of the Saint‐Venant Equations for Downscaling a Large‐Scale River Model

open access: yesWater Resources Research, Volume 59, Issue 2, February 2023., 2023
Abstract Large‐scale river models are being refined over coastal regions to improve the scientific understanding of coastal processes, hazards and responses to climate change. However, coarse mesh resolutions and approximations in physical representations of tidal rivers limit the performance of such models at resolving the complex flow dynamics ...

An Improved Physics‐Informed Neural Network Algorithm for Predicting the Phreatic Line of Seepage

open access: yesAdvances in Civil Engineering, Volume 2023, Issue 1, 2023., 2023
As new ways to solve partial differential equations (PDEs), physics‐informed neural network (PINN) algorithms have received widespread attention and have been applied in many fields of study. However, the standard PINN framework lacks sufficient seepage head data, and the method is difficult to apply effectively in seepage analysis with complex ...

Progressive Failure Analysis of Soil Slope with Strain Softening Behavior Based on Peridynamics

open access: yesAdvances in Civil Engineering, Volume 2023, Issue 1, 2023., 2023
In this study, the nonlocal, nonordinary state‐based peridynamics (NOSBPD) is introduced as a novel regularization technique to study the strain localization and progressive failure of soil slopes due to strain softening behavior. The NOSBPD formulations are introduced first, and then the strain‐softening Mohr–Coulomb model is incorporated into the ...

Regularized meshless method for antiplane piezoelectricity problems with multiple inclusions [PDF]

open access: yes, 2009
In this paper, solving antiplane piezoelectricity problems with multiple inclusions are attended by using the regularized meshless method (RMM). This is made possible that the troublesome singularity in the MFS disappears by employing the subtracting and
