A thermo-hydro-mechanical model for energy piles under cyclic thermal loading

This paper introduces a thermo-hydro-mechanical finite element model for energy piles subjected to cyclic thermal loading. We address four particular features pertaining to the physics of energy piles: three-dimensionality, embedded heat exchangers, soil constitutive modeling and pile–soil interface. The model is designed to capture the...

Freezing-thawing of porous media: An extended finite element approach for soil freezing and thawing

This paper introduces a thermo-hydro-mechanical computational model for freezing and thawing in porous media domains, with focus on freezing and thawing in soil. The model is formulated based on the averaging theory and discretized using a mixed discretization scheme, where the standard and extended finite element methods are simultaneously...

The frozen & unfrozen Barcelona Basic Model

The replication of the behaviour of frozen soils has been studied for decades. Many attempts have been undertaken to either develop new constitutive models or to improve already existing models to simulate the behaviour of frozen materials. To handle the challenges of ground freezing, cold regions engineering and periglacial processes, it is...
