3. Modeling A

Validation of joint \(\mathrm{2D}\) with the cohesive law CZM_EXP_REG

3.1. Characteristics of modeling

Modeling in plane deformations D_ PLAN for the elastic element.

Plane modeling for the joint element (keyword PLAN_JOINT).

3.2. Characteristics of the mesh

Number of knots: 6

The elastic element is a QUAD4.

The joint element is a degenerate QUAD4 (knots combined).

3.3. Results of modeling A

Load control is tested in \(I\) mode. In fact, this is the case where the overall response has a flashback (see internal note H-T64-2007-03420-FR for more details on this point).
