True Triaxial Strength Testing of Sandstones [PDF]
Proceedings, 2013 Laboratory rock mechanical tests allow estimation of rock strength and deformation behaviour under stress states similar to the in-situ conditions. In general, the in-situ stresses are described by three principal stresses, the vertical, maximum and minimum horizontal stresses.

True Triaxial Study on Aeolian Sand Subgrade
Journal of Physics: Conference Series, 2021 Abstract The drained shear tests of aeolian sand in Tengger Desert were carried out by using the British GDS true triaxial apparatus, and the shear strength and stress-strain relationships of aeolian sand were studied under the conditions of constant average principal stress and different intermediate principal stress coefficients.
