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 ...

Fractional Moment Theory for Anomalous Transport: A Unified Framework for Lévy Flights, Fractals, and Complex Dynamical Systems

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We develop a unified mathematical framework extending classical moment theory from discrete integer orders to a continuous spectrum of real orders f>0$$ f>0 $$, providing a systematic statistical characterization of complex systems exhibiting power‐law behavior.

Recent development in thermoelastic stress analysis

Proceedings of the 1998 International Conference on Quantitative InfraRed Thermography, 1998
Termoelastična analiza naprezanja (TAN) jedna je od metoda eksperimentalne mehanike, primjenjiva za kvalitativno i kvantitativno određivanje stanja naprezanja na površini ciklički opterećenih tijela mjerenjem intenziteta emitiranog infracrvenog zračenja.

Mixed‐Mode Stress Intensity Factor Evaluation via Thermoelastic Stress Analysis Including Non‐Adiabatic Correction

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 7, Page 2892-2907, July 2026.
ABSTRACT Characterization of the crack tip, such as the stress intensity factor (SIF), is a vital step for the assessment of fatigue crack growth and prediction of potential failure in engineering structures. This study investigates the use of thermoelastic stress analysis (TSA) for SIF evaluation, including a methodology for non‐adiabatic stress field

Seismic Velocity Variations Illustrate Hydrological and Ecohydrological Processes in a Mountain Watershed

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We employ passive seismic interferometry to study seismic hydrological responses in a snowmelt‐driven, semi‐arid catchment. Seismic velocity changes (dv/v) at 2–4 Hz and 4–8 Hz are analyzed from six stations along a hillslope transect between May and November 2023 and compared to precipitation, soil moisture, and groundwater level timeseries ...
