3. Modeling A

3.1. Characteristics of modeling

100 increments of the same size are used to calculate the time interval (\(\mathrm{0,}\mathrm{10000s}\)).

3.2. Characteristics of the mesh

Number of knots: 4

Number of meshes and types: 1 (QUAD4)

3.3. Tested sizes and results

Constraints \((\mathrm{MPa})\) at various times:

Instant	Reference	Aster	\(\text{\%}\) difference
100.2	14.315	14.329	0.01
1002	112.471	111.903	—0.5
10000	155.233	155.084	0.1

3.4. notes

The discrepancy observed is due to the discretization in time, which is relatively crude. The reference calculation (SIDOLO) is obtained with 500 increments.

By taking 500 increments, we get a maximum difference of \(\text{0.06\%}\).
