Drained triaxial compression

The results of the drained triaxial compression shear tests with the same initial states and different temperatures (22 °C and 90 °C) are compared for several overconsolidation ratios (OCR) (Figure 2). The initial confining pressure was 600 kPa.

The elastic-plastic constitutive model for triaxial simulations is introduced to illustrate the Mohr-Coulomb strength criterion and dilatancy. Figure 11 shows the soil model for the simulation of a displaeement-controlled drained triaxial test, where total stresses from the previous isotropic compression are taken as initial conditions. A vertical displacement...
