3. Modeling A

3.1. Characteristics of modeling

3D modeling

Item MECA_HEXA8

3.2. Characteristics of the mesh

Number of knots: 8

Number of meshes and types: 1 HEXA8

3.3. Tested features

The MAZARS_FO law of behavior combined with ELAS_FO.

3.4. Tested sizes and results

We compare damage \(D\) and stress \({\sigma }_{\mathit{zz}}\) at different times

Identification		Reference	Aster	% difference

3.5. note

In reality, the maximum damage, i.e. \(0.4626\), was reached at time \(t\approx 180s\). Then, it no longer evolves because of the decrease in \({B}_{c}\) when the temperature increases.
