1.3. Boundary conditions and loads#

1.3.1. A and B models#

Imposed displacement \((m)\):

  • side \(\mathit{ABCD}\): \(\mathit{DZ}=0\)

  • side \(\mathit{AEHD}\): \(\mathit{DY}=0\)

  • side \(\mathit{BFGC}\): \(\mathit{DY}=0.5\)

  • side \(\mathit{ABFE}\): \(\mathit{DX}=0\)

The displacement \(\mathit{DY}\) imposed on face \(\mathit{BFGC}\) varies progressively according to the function shown in the figure below.

1.3.2. C modeling#

Imposed displacement \((m)\):

  • side \(\mathit{ABCD}\): \(\mathit{DZ}=0\)

  • side \(\mathit{AEHD}\): \(\mathit{DY}=0\)

  • side \(\mathit{ABFE}\): \(\mathit{DX}=0\)

Pressure imposed \((\mathit{Pa})\):

  • side \(\mathit{BFGC}\): \(\mathit{PRES}=-520\)

The multiplier function of the pressure imposed on face \(\mathit{BFGC}\) as a function of time is represented in the figure below.
