8. Modeling I#
8.1. Characteristics of modeling#
It is a 2D modeling with D_ PLAN plane deformations, using linear meshes. We use the Signorin law of behavior from MFront with the GREEN_LAGRANGE model.
8.2. Characteristics of the mesh#
Number of linear elements: 228 TRIA3 Number of knots: 135
8.3. Tested sizes and results#
