500kN Load Frame
The 500kN Virtual Infinite Stiffness loading system (GDSVIS) is the premier load frame in the GDS VIS range. VIS stands for virtual infinite stiffness, it allows the axial loading system to operate as though it has infinite stiffness (zero system compliance). ...
Automatic Oedometer System (GDSAOS)
The GDS Automatic Oedometer System (GDSAOS) is the modern replacement for a traditional hanging weight oedometer. The GDSAOS is a self contained stepper motor driven unit that can be controlled either manually using its Smart Keypad or from a PC using the ...
Back Pressure Shearbox - High Pressure
The High Pressure Back Pressure Shearbox (HPBPS) is a high pressure version of our standard back pressures shearbox which also has the unique feature of being able to perform direct shear tests with precise back pressure control, for the direct control and ...
Consolidation Testing Systems (GDSCTS) including STDCTS and ADVCTS
The GDS Consolidation Testing System (GDSCTS) is a state-of-the-art, fully-automated consolidation testing system designed for soil. GDSCTS can run classic tests such as step loading to more advanced tests such as automated testing rate by controlled hydraulic ...
Constant Rate of Strain Cell (CRS)
The GDS Constant Rate of Strain Cell (CRS) is a load frame based one dimensional consolidation cell capable of applying back pressure and measuring pore pressures up to 1MPa (low pressure version) or 20MPa (high pressure version). Coupled with GDS controllers ...
Dynamic Back Pressure Shearbox
The Dynamic Back Pressured Shearbox (GDSBPS) is used for static and dynamic direct shear testing on soil specimens with control of sample pore pressures. The control of pore pressure during direct shear testing allows real-world situations to be modelled in ...
Electromechanical Dynamic Cyclic Simple Shear (EMDCSS)
A cylindrical soil specimen is laterally confined by Teflon coated low friction retaining rings, ensuring a constant cross sectional area. Vertical displacement may be prevented whilst shear force loading is applied, therefore constant volume conditions are ...
Electromechanical Dynamic Triaxial Testing System (DYNTTS) 2Hz, 5Hz or 10Hz
The Electromechanical Dynamic Triaxial Testing System (DYNTTS) is a combined triaxial cell and dynamic actuator, the axial force and axial deformation being applied through the base of the cell. The cell itself is screw-driven from an integral base unit housing ...
Enterprise Level Dynamic Triaxial System (ELDYN)
The GDS Enterprise level Dynamic triaxial testing system has been designed to fulfill the demand within the geotechnical laboratory testing industry for a lower cost, more basic dynamic triaxial testing system. ELDYN provides a simple route to allow cyclic ...
GDS Combined Advanced Dynamic Cyclic Simple Shear (ADVDCSS)
The GDS Combined Advanced Dynamic Cyclic Simple Shear (ADVDCSS) testing system is a new innovation by GDS in that it combines Simple shear and Triaxial testing without the use of a separate loadframe. The ADVDCSS uses our established technology of Electro-Mechanical ...
