3. Modeling A#

3.1. Characteristics of modeling#

Modeling: D_ PLAN (plane deformations)

Law of linear elastic behavior.

The pre-deformation introduced via the keyword PRE_EPSI in AFFE_CHAR_MECA is defined by an analytical function.

3.2. Characteristics of the mesh#

Quadratic mesh.

Number of knots: 853

Number of meshes and types: 359 TRIA6 and 27 QUAD8

Elements of BARSOUM are used for the meshes connected to the bottom of crack FOND_FISS.
