Saturated - Unsaturated Back Pressured Shearbox (GDSBPS)
The saturated GDS Back Pressured Shearbox (GDSBPS) is used for direct shear testing on soil specimens with control of sample pore pressures. Two versions of the GDS back pressured shearbox exist (Saturated and Unsaturated). Both versions allow the pore pressures ...
Triaxial Automated System (GDSTAS) including ELTAS, STDTAS, ADVTAS and HPTAS
The GDS Triaxial Testing System (GDSTTS) is a fully automated advanced triaxial testing system designed principally for stress path testing due to the direct actuation of axial stress through the hydraulically controlled ram in the base of each cell. GDSTTS ...
True Triaxial Apparatus (GDSTTA)
The GDSTTA allows independent control of stresses applied in three dimensions to a cuboidal soil sample. The ability to independently control the stresses applied in three dimensions allows the true stress-strain-strength behaviour of soil to be studied. Technical ...
Unsaturated Triaxial Testing of Soil
GDS Unsaturated Triaxial Testing of Soil (UNSAT) is an extension to traditional triaxial testing in that soils from above the water table may be tested under conditions approaching the in-situ stress state and degree of saturation or partial saturation. All ...
Variable Direction Cyclic Simple Shear
<p>The variable direction cyclic simple shear system (VDCSS) allows simple shear to be performed in 2 directions, rather than the standard one. This is achieved by having a secondary shear actuator that acts at 90 degrees to the primary shear actuator. The ...
