Modeling I
==============

Validation of the interface element PENTA15 with the cohesive laws CZM_OUV_MIX and CZM_TAC_MIX in open mode.


Characteristics of modeling
-----------------------------------

3D modeling for the elastic element.

3D modeling_ INTERFACE_S for the interface element


Characteristics of the mesh
----------------------------

Number of knots: 24

The elastic element is a PENTA15.

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


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:
