20. R modeling#
Validation of the interface element HEXA20 with the cohesive laws CZM_EXP_MIX in open mode.
20.1. Characteristics of modeling#
3D modeling for the elastic element.
3D modeling_ INTERFACE_S for the interface element
20.2. Characteristics of the mesh#
Number of knots: 32
The elastic element is a HEXA20.
The interface element is a degenerate HEXA20 (nodes combined).
20.3. 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
