Multi-Scale Thermo-Hydro-Mechanical Behavior of Saturated Earth Materials
… changes. Recorded temperature variations around thermo-active infrastructure and within the active layer of the permafrost reveal the cyclic and transient nature of these temperature changes. Previous studies on the thermo-mechanical behavior of soils did not consider the effect of the …

Coupled thermo-hydro-mechanical behavior of glacial tills in shallow geothermal systems
… analysis to characterize the coupled thermo-hydro-mechanical behavior of glacial tills in central Illinois and suggest a constitutive model for describing their short- and long-term behavior. Four specimens of predominantly fine-grained glacial till were collected in the upper 20 m …

Effect of Heating Rate on Thermally Induced Pore Water Pressure and Crack Evolution in Clay and Shales
This thesis investigates the hydrothermal behavior of clay shale samples, with a specific emphasis on how heating rates influence temperature distribution and the evolution of pore pressure under elevated temperatures. Clay shales, characterized by their extensive geological presence and low …
