1. Reference problem

1.1. Geometry A

The geometry is shown in the figure below:

The geometry is made up of:

• 10 discretes such as « DIS_T_D_N ». Four undeformable solids are represented by 4 \(\color{red}{\blacklozenge}\) and 1 \(\color{green}{\blacklozenge}\), which are connected with a « LIAISON_SOLIDE ». The \(\color{red}{\blacklozenge}\) are « DIS_T_D_N », the \(\color{green}{\blacklozenge}\) are « DIS_TR_D_L ».

• 2 discretes of the type « DIS_T_D_L » to represent the shock discretes \(\color{blue}{━━━}\) in the global coordinate system.

• 8 discretes of the type « DIS_T_D_L » to represent shock discretes \(\color{fuchsia}{━━━}\) in their local coordinate system.

1.2. Loads

1.2.1. Boundary conditions

The centers of the 4 undeformable solids represented by a \(\color{green}{\blacklozenge}\) are affected by a « DIS_TR_D_L » of which one of the nodes is embedded, the other being connected to 4 \(\color{red}{\blacklozenge}\).

We apply the displacements to the center of solid \(A\).
