True Triaxial Tests on Natural Shanghai Clay

2018
Drained true triaxial tests on undisturbed and remolded Shanghai silty clay were carried out to investigate the influence of intermediate principle stress on the strength and deformation of natural clay. Test results show that not only the shear strength, but also the volume change of Shanghai clay decreases with the increase of Lode angle θ. The shear

A True Triaxial Cell for Soil and Rock

1988
The design and performance of a membrane-piston, high-pressure (σ2 − σ3 ≦ 300 MN/m2) cell are presented. This device is similar to the one used for standard triaxial tests differing only in the stresses, σ2 and σ3, which are independently applied through flexible polyvinyl chloride (PVC) fluid cushions on prismatic specimens.

True Triaxial Stresses and the Brittle Fracture of Rock

Pure and Applied Geophysics, 2006
This paper reviews the efforts made in the last 100 years to characterize the effect of the intermediate principal stress σ2 on brittle fracture of rocks, and on their strength criteria. The most common theories of failure in geomechanics, such as those of Coulomb, and Mohr, disregard σ2 and are typically based on triaxial testing of cylindrical rock ...

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 ...
