Comparison and Correction of Multistage Triaxial Tests to Single Stage Triaxial Test for the Rock Mechanical Testing
… between two test protocols; the Single Stage Triaxial (SST) is where a constant confining stress is applied and the axial stress is raised until the sample fails. This is compared to the Multistage Triaxial (MST) test, where the sample is loaded to the point of positive dilatency (PPD) then …

Mechanical properties of tuffaceous rocks under triaxial conditions
… The study tested specimens of TCw tuff in triaxial compression to observe the effects of confining pressure, saturation, strain rate, and anisotropy on the compressive strengths and Young's Moduli of the specimens. Test results have shown that increasing the confining pressure increased the …

Assessment of the triaxial falling head permeability testing technique
… each parameter on the results obtained from the triaxial falling head permeability test. The conclusions reached in this report indicate that to obtain the coefficient of permeability for the saturated condition, the falling head tests should be performed in a triaxial cell"--Abstract, page ii.
