3. Modeling A

3.1. Characteristics of modeling

• rigid rotation phase \(0\mathrm{\le }t\mathrm{\le }1s\)

• traction phase: \(\mathrm{1s}\mathrm{\le }t\mathrm{\le }\mathrm{2s}\)

• boundary conditions (TYPE_CHARGE: “DIDI”)

• loading: pressure (negative) on side \(\mathrm{[}\mathrm{2,}\mathrm{4,}\mathrm{8,}6\mathrm{]}\)

(PRES_REP): mesh \(\mathrm{[}\mathrm{2,}\mathrm{4,}\mathrm{8,}6\mathrm{]}\) (QUAD4): \(\mathit{PRES}\mathrm{=}–26610.3(t–1)\).

3.2. Characteristics of the mesh

Number of knots: 8	Number of stitches: 2
	1 HEXA8 1 QUAD4

3.3. Tested sizes and results

The values are tested at the end of loading (\(t\mathrm{=}\mathrm{2s}\))
