4. B modeling

4.1. Characteristics of modeling

Fragile modeling is done with modeling AXIS_JOINT and law CZM_LIN_REG. Volume elements are modeled with model AXIS.

4.2. Characteristics of the mesh

The mesh is linear.

Count of elements: 280 QUAD4.

Number of interface elements: 15 QUAD4.

4.3. Tested sizes and results

Non-regression test: diametral contraction (\(\mathrm{-}2\mathrm{\times }\mathit{DX}\) from point \(B\)), traction force (the resultant \(\mathit{DY}\) of REAC_NODA out of \(\mathit{CD}\) multiplied by \(2\pi\)) as a function of the tensile displacement \(\mathit{DY}\) (on \(\mathit{CD}\)).

For a shift from \(\mathrm{0,6}\mathit{mm}\) according to \(Y\) to \(\mathit{CD}\)

Size tested	Code_Aster	Tolerance ( \(\text{\%}\) )
Contraction (\(\mathrm{mm}\))	0.253835	0.10
Force (\(\mathit{kN}\))	25.18191	0.10

For a shift from \(\mathrm{0,8}\mathit{mm}\) according to \(Y\) to \(\mathrm{CD}\)

Size tested	Code_Aster	Tolerance ( \(\text{\%}\) )
Contraction (\(\mathrm{mm}\))	0.254455	0.10
Force (\(\mathrm{kN}\))	7.112202	0.10

4*Summary of results

Non-regression tests are carried out for both models. In addition, comparison tests with the Rousselier model are carried out for modeling A.
