21. S modeling#

Validation of the interface element PENTA15 with the cohesive laws CZM_EXP_MIX in open mode.

21.1. Characteristics of modeling#

3D modeling for the elastic element.

3D modeling_ INTERFACE_S for the interface element

21.2. Characteristics of the mesh#

Number of knots: 24

The elastic element is a PENTA15.

The interface element is a degenerate PENTA15 (nodes combined).

21.3. Tested sizes and results#

The remark on control mentioned for modeling A also applies to this modeling.

We check the analytical expression of the displacement as a function of the force imposed as well as the resulting constraints and internal variables for a percentage of energy dissipated of 0.3
