7. Summaries of results

It is possible to compare the calculation time for the same number of propagation steps (15) of the three methods.

Mesh	Method	Time ( \(s\) )
\(40\times 101\)	Meshing	21.7
	Simplexe	18.8
	Upwind	23.7
	geometrical	21.2

The results make it possible to validate on a simple case the calculation of stress intensity factors in \(I\) mode for the elements X- FEM for the four meshing, simplex, upwind and geometric methods.
