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


Characteristics of the mesh
----------------------------

Number of knots: 9368

Number of meshes and types: 3350 TRIA6, 800 QUAD8


Tested sizes and results
