v1.01.287 ZZZZ287 — Basic validation of the POST_RUPTURE operator

Summary:

The purpose of this test is to validate the POST_RUPTURE operator in an elementary way. This test has no physical meaning, it is essentially a computer test.

Various operations are tested:

• normalization of the curvilinear abscissa,

• calculation of the angle of bifurcation,

• calculation of the crack advance increment in fatigue with the Paris law with and without a threshold,

• calculation of the equivalent stress intensity factor,

• calculation of \({(\Delta K)}_{\mathit{eq}}\) used for propagation in variable amplitude,

• zeroing the negative values of the stress intensity factors \({K}_{1}\) and calculating the new recovery rate G using the Irwin formula.

This test contains two models:

• Modeling A considers a crack with a background.

• Model B includes a crack with two bottoms.

This documentation is deliberately brief.
