Damage detection in hot‐dip galvanized structural steel using AC potential drop method Schädigungsdetektion an feuerverzinktem Baustahl mittels Wechselstrom‐Widerstandsmessung

Materialwissenschaft und Werkstofftechnik, EarlyView.
This study demonstrates that the alternating current potential drop (ACPD) method detects early fatigue damage in hot‐dip galvanized structural steel. Analysis of the voltage gradient (du/dN) enables time‐resolved differentiation between coating and substrate cracks.

Nordgren PINNs to VQE: Advancing Hydraulic Fracturing Simulations in Shale Reservoirs

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This study advances hydraulic fracturing simulations in shale reservoirs using two computational paradigms, Physics‐Informed Neural Networks (PINNs) and the Variational Quantum Eigensolver (VQE). PINNs were employed to solve Nordgren's equation, which governs fracture width evolution, by embedding physical laws into the neural network ...

A Geometrically Regularized Gradient‐Damage Model With Orthogonality‐Based Energy Split for Dynamic Anisotropic Compression‐Shear Fracture

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This study proposes a novel geometrically regularized gradient‐damage model for simulating dynamic mixed‐mode fracture in orthotropic materials with tension–compression asymmetry. In this model, a thermodynamic framework is formulated by incorporating damage dissipation into internal energy evolution, from which the constitutive relation and ...

Influence of Relative Permeability Formulations on Hysteretic Seepage in Infinite Slopes

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The paper investigates the impact of two classical relative permeability formulations, one expressed in terms of pore water pressure and the other in terms of degree of saturation, on the predicted seepage in an infinite slope subjected to surface pore pressure variations.

Using synthetic models to understand the detecting ability of ground‐penetrating radar for water‐conducting structures in the bedrock of formerly glaciated site

Near Surface Geophysics, EarlyView.
Abstract Utilizing synthetic models for the interpretation of ground‐penetrating radar (GPR) profiles can aid in the detection of hydrogeological structures by identifying their signatures. In this study, finite difference (FD) forward modelling was used to understand the detection ability of 50 MHz GPR for (1) the quaternary deposit–bedrock contact ...
