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
