Using the stress-strain relations that are obtained during cyclic loading triaxial compression test
, the damage variable D of sandstone specimens under different confining pressures are deduced respectively using Eq.
 carried out a triaxial compression test
of granite treated by heating and rapid cooling.
Therefore, according to the measured data in the triaxial compression test
and the formula (21), the elastic modulus of each modified soil in Table 1 can be concluded.
 accomplished the triaxial experiments of two series of loading on the sand by use of conventional triaxial compression test
apparatus and studied the stress history and lithology, over consolidation ratio.
The experimental studies include true triaxial compression test
and photoelastic test.

Development of new triaxial compression test
apparatus for geomaterials on industrial X-ray CT scanner.
The result of cyclic shear stress of torsional single shear test is lower than that of triaxial compression test
, while the mean principal stress is dependent of initial shear stress.
The relationship between dry unit weight and internal friction angle was identical for different strain rates, regardless of water content, as shown by the triaxial compression test
results plotted in Figure 4.
