Calibrating Thermomechanical Triaxial Cells for Transient Thermal Loads

This paper presents a method to integrate the thermal calibration of triaxial cells into the testing procedure, facilitating accurate measurements of thermally-induced pore pressures and volumetric strains during transient thermal loads. For this purpose, a modified thermomechanical triaxial cell that can control the specimen temperature at a specified rate is utilized. Unlike other thermomechanical systems, a separate backpressure pump is...
