SSH-100 Simple Shear Testing System
Based on our external wall triaxial system, the GCTS SSH-100 Simple Shear Testing System is designed to yield accurate results in tests that cannot be done using other systems (e.g., consolidation can be done at K values other than K0).
The design of the GCTS Simple Shear Testing System (SSH-100) is based on our external cell wall triaxial system. The apparatus has a fixed top and a sliding bottom base mounted on special linear bearings to help with specimen loading and unloading. The system also has a stiff internal support to minimize lateral compliance of the top cap.
One of the main advantages of the GCTS Simple Shear Testing System is that the apparatus does not require a reinforced membrane, as lateral support is provided via the confining pressure, which can be servo-controlled. This means that consolidation can be done at K values other than K0. However, this device also includes Teflon-coated thin rings to externally reinforce the standard latex membranes to ensure KO consolidation.
The SSH-100 is capable of testing 100 mm (4 in.) and 71 mm (2.8 in.) diameter specimens. Because the internal lateral support is provided by the confining pressure, specimen of different heights can be tested. This means that the system can be used to test either simple shear or triaxial test specimens with heights up to 2.5 times their diameter.
