The GCTS Rock Direct Shear System is a versatile “turnkey” system for determining shear strength of a wide range of intact or jointed rock specimens. The rock specimen configurations include cylindrical cores, cubes, prisms, and rock fragments. This system features state-of-the-art, electro-hydraulic, closed-loop digital servo control of shear and normal loads for test automation. The system includes automatic data acquisition and real-time graphics with very precise sensors and 16-bit resolution.
The GCTS system is easily programmable to measure residual shear strength during or after any number of cycles specified by the user. The GCTS software calculates automatically the corrected specimen area, the normal and shear stresses, shear deformation, and the average normal deformation. Loads, stresses or deformations for both the shear and normal
