			`phase_field_notch.cc` shows hot to set a quasi-static fracture simulation with phase-field. The geometry of the solid is a square plate with a notch. The loading is an imposed displacement at the top of the plate (mode I).

			Notched plate with boundary conditions and imposed displacement.

			In addition, this example shows how to extract clusters delimited by the mesh boundaries and elements with damage values beyond a threshold. This can be useful to extract fragments after crack propagation.
