1. Reference problem

1.1. Geometry A

The geometry is shown in the figure below:

The geometry is made up of:

• 10 discrete ones. Two 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 ».

• a discrete of the type « DIS_T_D_L » to represent the shock discrete.

1.2. Loads

1.2.1. Boundary conditions

The centers of the 2 undeformable solids are represented by a \(\color{green}{\blacklozenge}\) affected by a « DIS_TR_D_L » of which one of the nodes is embedded, the other being connected to 4 \(\color{red}{\blacklozenge}\).

At the center of one of the solids a displacement is applied. This movement must be found on the center of the other solid, in games \(e_x\), except \(e_y\), as soon as the contact is activated.
