Contacts input

Providing we choose beam elements to model the sheeting wall it is necessary to use contact elements with plastic material model (Mohr-Coulomb), which ensures that the soil-beam interaction is properly addressed.

The "Contact type" input mode combined with the "Add" button allow for defining the required parameters. In the present example we assume that the contact material parameters correspond to about 30% of shear strength parameters of the surrounding soil (δc=0.3, δη=0.3). Standard setting is considered for the elastic stiffnesses kn and ks (10000 kN/m3).

The next step requires entering free points and lines to represent the sheeting wall.
