True Triaxial Systems
The Advanced True Triaxial Test System has the defining characteristic that all three principal stresses can be controlled independently, unlike conventional triaxial apparatus with just two stresses. This allows a wide range of complex stress paths to be performed. This dynamic cyclic system is powered by advanced electromechanical actuators or optional hydraulic actuators and is an extremely sophisticated research tool. Vertical and one horizontal axis are loaded via the dynamic actuators (axis 1 and 2), stress control is provided for the 2nd horizontal axis, (axis 3) via cell pressure.
