Poromechanical and Crack Evolution of Olivine‐Rich Rock During Serpentinization
Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract Serpentinization alters the strength, fracture behavior, and rheology of ultramafic rocks, yet the coupled evolution of mineral reactions, cracking, and mechanical softening remains poorly constrained. We experimentally simulated serpentinization in dunite at 220°C and 15 MPa for 14 and 30 days and compared the reacted specimens with dry heat ...

Design of a Hydroelectronic Solar‐Tracking System for Solar Panels
Energy Science &Engineering, Volume 14, Issue 5, Page 2600-2625, May 2026.A prototype of a passive solar‐tracking system utilizing buoyant force based on water level was developed, and its MATLAB/Simulink model was implemented. This study is expected to encourage researchers to design solar‐tracking mechanisms using metals with different thermal expansion coefficients, air, oil, and other fluids. ABSTRACT This study presents

Mathematical Problems in Engineering, 2020 This paper proposes a new transmission scheme of hydromechanical continuously variable transmission (HMCVT) for tractors. The HMCVT has 4 working ranges in each of the front and rear directions. The speed characteristic and the torque characteristic of HMCVT are theoretically derived.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract Underground hydrogen storage in porous formations (UHSP) subjects reservoir rocks to long‐term cyclic effective stress variations, potentially altering storage capacity and injectivity. In this study, we conduct hydrostatic loading tests on 18 Saint‐Maximin limestone (SML) samples (connected porosity 31.9%–37.2%) under various loading paths ...

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract While large earthquakes can alter groundwater systems far from the epicenter, their hydromechanical changes remain elusive. We investigate the 2011 Mw 9.0 Tohoku earthquake's impact on a deep well‐aquifer system ∼2,000 km from the epicenter. By employing the groundwater tidal and barometric pressure response methods, we perform tidal response ...

A Parallelized 3D Geomechanical Solver for Fluid‐Induced Fault Slip in Poroelastic Media
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 5, Page 2570-2586, 10 April 2026.ABSTRACT We present a fully implicit formulation of coupled fluid flow and geomechanics for fluid injection/withdrawal in fractured reservoirs in the context of CO2$\textrm {CO}_2$ storage. Utilizing a Galerkin finite‐element approach, both flow and poroelasticity equations are discretized on a shared three‐dimensional mesh.

Configuration of the Power Reflux Hydro-Mechanical Transmission System
ActuatorsThe hydro-mechanical transmission system (HMTS) operates either in power split transmission mode (PSTM) or power reflux transmission mode (PRTM). Although PRTM is often ignored as a transition mode, this study reveals that the HMTS operating in the PRTM ...

A Thermodynamic Framework for Turing‐Type Instabilities in Porous Media: Part I Theory
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract Pattern formation in geological materials is commonly described using analogies to Turing‐type reaction–diffusion systems, yet a unifying thermodynamic explanation remains elusive. Here we develop a multiscale, thermodynamically consistent framework for pattern‐forming instabilities in porous media undergoing coupled thermo–hydro–mechanical ...
