Rock mechanical properties under reconstructed deep in situ thermo–hydro–mechanical conditions: Implications for CO₂‐related injection scenarios

Deep Underground Science and Engineering, EarlyView.
The graphical abstract illustrates a reconstructed in situ thermo‐hydro‐mechanical (THM) framework in which porosity serves as the central variable linking stress, pore pressure, and temperature to evolving mechanical properties of rocks. Under burial conditions, in situ stress, pore pressure, and temperature jointly govern volumetric strain and ...

Nonlinear computation of axisymmetric solid rubber deformation

Computer Methods in Applied Mechanics and Engineering, 1988
The paper is of a technical nature and is devoted essentially to the detailed derivation of the element gradient vector and stiffness matrix for the nonlinear finite element analysis of axisymmetric rubber. The technique, which is based on the discrete sampling of the total potential energy of the deformed solid, is a natural extension of the one ...

Multi‐factor coupling effects in hydraulic fracturing of laminated shale: Experimental insights and physics‐informed neural network‐driven optimization

Deep Underground Science and Engineering, EarlyView.
This study establishes a multi‐factor coupling framework for predicting breakdown pressure in laminated shale by integrating experimental hydraulic fracturing tests, physics‐informed neural networks (PINNs), and Sobol sensitivity analysis. It reveals how differential stress, the bedding dip angle, and the injection rate interact to influence fracture ...

Modeling proppant transport and settling in a 3D propagating fracture

Deep Underground Science and Engineering, EarlyView.
A versatile multiphysics tool is presented for simulating the complex processes involved in hydraulic fracturing treatments. The model couples fracture opening and propagation, variable‐density slurry flow, and proppant particle transport within the multiphysics object‐oriented simulation environment framework, based on two‐phase mixture equations and ...

Arterial Perivascular Space‐Mediated Solute Transport in the Mouse Brain

Exploration, EarlyView.
The mechanisms underlying solute clearance from the brain parenchyma remain debated, with competing hypotheses involving bulk cerebrospinal fluid flow versus perivascular transport. Using multimodal in vivo imaging and computational modeling in mice, this study demonstrates that arterial pulsation drives bidirectional solute movement within the ...

Axisymmetric alternating direction explicit scheme for efficient coupled simulation of hydro-mechanical interaction in geotechnical engineering—Application to circular footing and deep tunnel in saturated ground

Journal of Rock Mechanics and Geotechnical Engineering, 2018
Explicit solution techniques have been widely used in geotechnical engineering for simulating the coupled hydro-mechanical (H-M) interaction of fluid flow and deformation induced by structures built above and under saturated ground, i.e. circular footing

Wide‐range and high‐resolution Young's modulus sensing enabled by a complementary indentation‐protrusion architecture

FlexMat, EarlyView.
A tactile sensor integrating indentation and protrusion sensing within a single platform enables accurate perception of object Young's modulus. This complementary architecture expands the detectable Young's modulus range to 25.8–2639.2 kPa and achieves an object recognition accuracy of 94.27%, outperforming indentation‐only (84.59%) and protrusion‐only

Compressive Deformation Analysis of Alginate-Poly(L)lysine-Alginate (APA) Microcapsule

Journal of Biomechanical Science and Engineering, 2013
An analysis of the compressive deformation of alginate-poly(L)lysine-alginate (APA) microcapsules by two rigid parallel plates was performed under the assumptions that the bending stiffness and permeability of the membrane were negligible.
