A true triaxial cell for testing cylindrical rock specimens

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1995
In this paper a new true triaxial cell, capable of routine testing of cylindrical rock core plugs under realistic 3-D polyaxial stress states, has been conceived by the author, the design of which is outlined. The cell presents the opportunity to develop enhanced realism when testing cylindrical rock specimens.

Study of Artificial Structural Loess under the True Triaxial Tests

Advanced Materials Research, 2013
Structure characteristic is the essential property of natural soils. The paper developed an indoor method of artificial structural loess, and studied on the true triaxial tests of artificial structural loess on the base of improving the original true triaxial apparatus. The results show that it is reasonably reliable of this artificial method.

Stress–strain behaviour of unsaturated soil in true triaxial tests

Canadian Geotechnical Journal, 2002
A suction-controlled true triaxial apparatus for unsaturated soil was developed from the existing true triaxial apparatus for sand by attaching a device to supply matric suction to specimens. Using the developed apparatus, true triaxial tests (σ1 [Formula: see text] σ2 [Formula: see text] σ3; where σ1, σ2, and σ3 are the three different principal ...

Development of a True Triaxial Testing Facility for Composite Materials

2000
An electromechanical testing facility capable of applying any combination of tensile and/or compressive forces to three mutually orthogonal axes of a thickness-tapered composite cruciform specimen was designed, fabricated, assembled, and evaluated. Any stress ratio in biaxial (σ1 - σ2) or triaxial (σ1 - σ2 - σ3) stress space can be explored using this ...

The Danish Rigid Boundary True Triaxial Apparatus for Soil Testing

Geotechnical Testing Journal, 2002
Abstract The intermediate principal stress plays an important role for the stress-strain behavior of soils. The effect of the intermediate stress cannot be examined in the conventional triaxial apparatus since axisymmetric stress states are prescribed in it.
