Adiabatic temperature rise is a damage mechanism in frozen soil that occurs under impact loading, yet it is rarely incorporated into discrete element method (DEM) modeling frameworks. To address this limitation, a thermal–mechanical parallel-bonded stress corrosion model was developed within the particle flow code (P...
Freezing soil presents unique challenges in understanding the coupled mass and energy dynamics within the Earth’s critical zone. This paper focuses on the thermodynamic energy budget of pore water within a rigid soil skeleton, and presents a thermodynamic framework for analysing phase transitions in soil–water-ice syst...
Recently, cryostress has been conceptualized as part of effective stress to describe the shear strength of soil under frozen conditions. Cryostress is defined as the interparticle stress due to the formation of ice grain and is a characteristic function of temperature. Three physicochemical soil–ice–liquid interactio...
The coupled thermo–hydro–mechanical–chemical equations are developed for reactive fractured rock with double porosity. The constitutive equations explicitly account for the effects of solid‐phase reactions (e.g., dissolution, precipitation) on the stress‐strain response and porosity evolution by reactions in both the f...
Frost heave and thaw settlement from cyclic freezing and thawing (F-T) damage infrastructure like roadbeds in cold regions. Geogrids can help control this damage, but their mechanism in complex F-T processes is unclear. This study uses lab tests to examine how geogrids affect moisture, temperature, and deformation in l...
