1.3. Initial conditions, boundary conditions, and loading#

Phase 1:

The sample is brought to a homogeneous state:

_images/Object_1.svg

, by imposing the corresponding confinement pressure on the front, right lateral and upper faces. The movements are blocked on the back sides (

_images/Object_2.svg

), left lateral (

_images/Object_3.svg

) and lower (

_images/Object_4.svg

).

Phase 2:

We keep the movements blocked on the rear faces (

), left lateral (

_images/Object_6.svg

) and lower (

_images/Object_7.svg

), as well as the confinement pressure on the front and right lateral faces. An imposed displacement is applied on the upper face:

, so as to obtain a deformation

(counted from the start of phase 2).
