Porothermoelasticity is a multidisciplinary research field that investigates the coupled response of porous materials subjected to simultaneous thermal, hydraulic, and mechanical stimuli. It specifically examines the intricate interactions between temperature fields, pore fluid pressure distribution, and the elastic deformation of the porous solid skeleton, often incorporating phenomena like thermo-osmosis, thermal expansion, and phase change under the principles of mass, momentum, and energy conservation. This field is crucial for understanding and modeling the behavior of diverse porous media, including geomaterials, concrete, and biological tissues, under complex environmental or operational conditions.
