Shear Testing: Combined Advanced Dynamic Cyclic Simple Shear
The GDS combined Advanced Dynamic Cyclic Simple Shear (ADVDCSS) is a testing system that can be used for dynamic cyclic, simple shear and dynamic triaxial testing. The ADVDCSS allows a principal stress directions to continuously rotate through 90 degrees, giving the ability to simulate the stress common to many geotechnical problems, including earthquake loading. Then, by moving the machine into ‘triaxial mode’ and installing the longer cell w..

Shear Testing: 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 the laboratory. This dynamic version of the device allows a landslide to be modelled as it quickly gains velocity after the intial moment of failure. Cyclic direct shear testing is also..

Shear Testing: GDS Back Pressured Shear Box
The Back Pressure Shearbox (BPS) has the ability to performs direct shear tests with precise back pressure control, for the recreation and measurement of realistic slope failures.  The BPS range includes a saturated version (control of pore water pressure), an unsaturated version (control of both pore water and pore air pressure) and a dynamic version (See the following page).   Features & Benefits ..

Shear Testing: GDS Electro-Mechanical Dynamic Cyclic Simple Shear
The GDS Electromechanical Dynamic Cyclic Simple Shear Device (EMDCSS) is for simple shear testing only. It is capable of carrying out dynamic cyclic tests from small strain (0.005% shear strain amplitude) to large strain (10% shear strain amplitude), as well as extremely accurate quasi-static testing. This is the choice for a no-compromise simple shear machine with the greatest range of testing capability. The perfect choice for advanced comme..

Shear Testing: GDS Large Automated Direct Shear System (300mm)
GDS Large Automated Direct Shear System (GDSLADS) is an electromechanical direct shear testing device for large samples, up to 300mm square or round. Different sample sets can be used to achieve the following types of testing in one system.   Standard Direct Shear up to 300x300mm. Geomembrane Shear test. Rock Mechanics sample set. Features & Benefits Electro..

Shear Testing: GDS Shearbase System
he GDS Shearbase System (GDSSS) is an electro-mechanical shear testing device that can be configured as either a simple shear or direct shear apparatus. The benefit of this apparatus is that the conversion between simple shear and direct shear is simple and therefore if both options are not supplied at time of build the missing option can be supplied at a later date. Features & Benefits This desktop apparatus comes w..

Shear Testing: Interface Shear Tester
The Interface Shear Tester is a CRS consolidation cell with the additional ability that the base pedestal may infinitely rotate. The internal load cell measures both the axial force on the specimen as well as the torque generated. The system is designed to test the shear interface between the sample and the top-cap.  Customers may bond specific materials to the top-cap for testing.   Features & Benefits ..

Shear Testing: Shearbox Upgrade
GDSADS stands for Automated Direct Shear, and allows existing shearboxes from other manufacturers to be upgraded to be automated. Many shearboxes from other manufacturers can be controlled by the GDSLAB software and so full automation may be achieved with the addition of GDSLAB and transducers.   ..

Shear Testing: Variable Direction Cyclic Simple Shear
The variable direction cyclic simple shear system (VDCSS) allows simple shear to be performed in two directions, rather than the standard simple direction. This is achieved by having a secondary shear actuator that acts at 90 degrees to the primary shear actuator. The VDCSS is similar in principle to the EMDCSS machine, except for the additional horizontal axis. All standard simple shear tests can be performed.  When used as a va..
