Phase 1:
The sample is brought to a homogeneous state of effective constraints:
, by imposing the corresponding total pressure on the front, right lateral and upper faces and by imposing zero water pressures everywhere. The movements are blocked on the back sides (
), left lateral (
) and lower (
).
Phase 2:
We keep the movements blocked on the rear faces (
), left lateral (
) and lower (
). On all sides, hydraulic flows are zero.
An imposed displacement is applied to the upper face in order to obtain a deformation.
(counted from the start of phase 2). On the front and right lateral faces, limit conditions under total stress are imposed:
