Implementation of a new thermo-viscoplastic soil model using FEniCS platform

Paper i proceeding, 2024

The heating and cooling processes (e.g., imposed by energy geostructures)
may cause undesired displacement of soil, which in turn may impact the long-
term stability of the geothermal structures. This is true especially those in-
stalled in sensitive clays due to the high dependence of their creep behaviour
on the temperature. This paper presents a numerical implementation algorithm
for an enhancement of an existing hydro-mechanical model into a Finite Ele-
ment code based on FEniCS platform. It also includes a validation example
against experimental data of thermal oedometer tests. The quantitative com-
parison to experimental results supported the suitability of the framework.
