3. Modeling A

3.1. Characteristics of modeling

Modeling in plane deformations (keyword D_ PLAN) for the cube with side 1.

Plane crack modeling (keyword PLAN_JOINT) for the joint element.

The cube is a \(\mathit{QUAD4}\).

The joint element is a degenerate \(\mathit{QUAD4}\) (knots combined).

3.2. Characteristics of the mesh

Number of knots: 6

Number and type of meshes: 2 \(\mathit{QUAD4}\).
