3. Modeling A: « rectangle » crack

This modeling tests the « rectangle » crack.

3.1. Characteristics of the mesh

The initial mesh is healthy: it is discretized in \(40\mathrm{\times }5\mathrm{\times }40\) HEXA8.

3.2. Tested sizes and results

The test focuses on the value of \(\mathit{lst}\) at points \(\mathit{P4}\) and \(\mathit{P5}\).

Identification	Reference type	Reference value	Tolerance
\(\mathit{lst}(\mathit{P4})\)	“ANALYTIQUE”	0.884077	10-12
\(\mathit{lst}(\mathit{P5})\)	“ANALYTIQUE”	0.2	10-12
