v7.33.112 WTNA112 — Thermal pressurization of a saturated, undrained cylindrical specimen

Summary:

This is a saturated and elastic THM problem. The temperature of an undrained sample maintained under constant confinement (constant total stress at the edge) is increased. The resulting water pressure then varies linearly with the temperature according to a thermal pressurization coefficient that is calculated analytically. The solution obtained here is therefore to be compared with an analytical solution.
