On the contrary, in the unsaturated systems volume change measurements are complicated by the compressibility of air. If an increase of confining pressure is applied to an unsaturated sample, a movement of water out of the sample will occur but at the same ...
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 ...
In conventional triaxial testing the determination of axial stiffness is based on external measurements. This method brings errors due to sample bedding effects of the porous stones on either end of the sample and to the loading system and load measuring system. ...
Used for the measurement of cell pressure, back pressure, pore pressure (water or air).
The cell essentially consists of a transparent polycarbonate chamber which has a piston assembly fit to the top and a double flange base fit to the bottom. Three (or six) simple thumbscrew are used to clamp the upper part of the cell to the base, which make ...
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 ...
These advanced models are particularly suited for use with Bender elements. The design of the cell ensure vertical alignement of the cell ram by clamping the Perspex wall separately from the cell top. The cell wall is banded to prevent excessive expansion ...
The TRITECH range of triaxial load frames, has been designed to be also used as part of a computer-controlled triaxial system or as a stand-alone unit. The RS 232 interface enables the TRITECH to be used for automatic Stress Path Tests.
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 ...
