4. B modeling#
4.1. Characteristics of modeling#
3D Modeling_ GRAD_INCO.
4.2. Characteristics of the mesh#
Number of knots: 128.
Number and types of meshes: 10 HEXA20, 51 QUAD8, 84 SEG3.
4.3. Tested sizes and results#
The following values are recovered at time 0.5 and 0.8: the stress \({\mathrm{\sigma }}_{\mathit{xx}}\) (“SIEF_ELGA”, “”, “SIXX”), the work hardening variable \(\mathrm{\kappa }\) (“VARI_ELGA”, “V1”) and the porosity \(f\) (“VARI_ELGA”, “V2”) and the porosity (“”, “V2”) of two integration points. The first integration point is the one closest to node \(A\) (we note it \(G1\)), the second is the one farthest from node \(A\) (we note it \(G2\)).
The following table summarizes the values obtained by the Z-set finite element calculation software.
