a) After an axial strain Aɛa-0.9%, the deviatoric stress is measured to be 90 kPa. For this stage of the test, calculate the values of Ap, Ap', Aoa', Aor', Aơa, and Eu. b) At this time, the axial stress and cell pressure are kept constant, and the sample is allowed to drain so that the pore pressures dissipate and the sample undergoes a volumetric strain Aev-0.3%. What are the values of Aoa', AO, Aea, and Aer for this stage of the test, and what are the value of the elastic constants K' and G'? a) After an axial strain Aɛa-0.9%, the deviatoric stress is measured to be 90 kPa.
