10. H modeling#
Validation of the interface element HEXA20 with the cohesive laws CZM_OUV_MIX and CZM_TAC_MIX in open mode.
10.1. Characteristics of modeling#
3D modeling for the elastic element.
3D modeling_ INTERFACE_S for the interface element
10.2. Characteristics of the mesh#
Number of knots: 32
The elastic element is a HEXA20.
The interface element is a degenerate HEXA20 (nodes combined).
10.3. Tested sizes and results#
The remark on control mentioned for modeling A also applies to this modeling.
The results are identical in mode I for both laws, we only present those obtained with CZM_OUV_MIX:
