3. Modeling A

3.1. Characteristics of modeling

The crack is modelled by a notch with a radius of 100 microns. The \(2\mathrm{mm}\) long zone \(\mathrm{Ze}\) is divided into layers of 20 micron thick elements (also called « chips »).

3.2. Characteristics of the mesh

Number of knots: 9368

Number of meshes and types: 3350 TRIA6, 800 QUAD8

3.3. Tested sizes and results
