RPS-100 Polyaxial / True Triaxial Testing System
The GCTS RPS-100 Polyaxial Testing System offers a precise analysis of the intermediate principal stress effect on rock engineering behavior and thus adequately describes the strength of rock under a general system. Many add-ons can supplement this system to enhance and broaden testing.
The GCTS RPS-100 Rock Polyaxial System can be used to study the intermediate principal stress effect on rock engineering behavior and describe adequately the strength of rock under a general system of Polyaxial compressive stresses. Syringe pressure intensifiers are used to apply σ1, σ2 and σ3 independently with measurement of volume/deformation change.
GCTS also offer semi-circular platens to test cylindrical specimens together with GCTS hydraulic fracturing fixtures and approximate the effects of anisotropic stress state on borehole stability. Even though the stress state applied with these semicircular loading jacks is not uniform, it is much easier to prepare and test cylindrical specimens.
Ultrasonic sensors can also be provided to study the effects anisotropic stress conditions on compression and shear wave velocities. Velocities for all three axes can easily be measured during Polyaxial tests with this option.
