Model:STDTTS ADVTTS HPTTS
Use:The GDS Triaxial Testing System (GDSTTS) is a fully automated triaxial testing system designed principally for stress path testing.
Standard:ASTM D-4767; ASTM D-7181
Product Code : GDSTTS
The GDSTTS is based on the classic Bishop & Wesley type stress path triaxial cell which controls stress directly on the sample. The system can be configured using Enterprise, Standard or Advanced level controllers. The 38/50mm cell is for up to 7kN axial force, with the larger 70/100mm cell up to 25kN. This is the system of choice for teaching laboratories and researchers.
Key features | Benefits to the user |
---|---|
Each system may be configured exactly to the customer’s specification and budget: | Users can choose the transducers, pressure controllers, triaxial cell or just parts to integrate into existing equipment to build their ideal set-up. |
Direct actuation of axial stress through the hydraulically controlled ram in the base of each cell: | The Bishop and Wesley cell is designed specifically for stress path testing. Direct axial stress application means greater accuracy for stress control. |
GDSTTS can run advanced tests: | Tests such as stress paths, slow cyclic and K0, all under PC control. |
Standard through to advanced configurations: | GDS provide advanced (ADVTTS) systems with all the features of the standard systems but with higher accuracies and resolution. |
May be upgraded at any time: |
Additional transducers, software modules, bender element testing and unsaturated testing makes the system future proof.
