11. Modeling I#
11.1. Characteristics of modeling#
3D Modeling_ GRAD_HHO - LINEAIRE.
11.2. Characteristics of the mesh#
Number of knots: 20.
Number and types of meshes: 1 HEXA20, 6 QUAD8, 6, 12 SEG3.
11.3. Tested sizes and results#
The problem considered here is homogeneous and identical to problem \(C\) (modeling \(C\)). the constraints (or internal variables) are therefore identical at the various gauss points.
The following values are recovered at time 0.5 and 0.7: the component \({\mathrm{\sigma }}_{\mathit{yy}}\) of the stress tensor (“SIEF_ELGA”, “SIYY”), the work-hardening variable \(\mathrm{\kappa }\) (“VARI_ELGA”, “V1”) and the porosity \(f\) (“VARI_ELGA”, “V2”) and the porosity (“”, “V2”).
The following table summarizes the values obtained by the Z-set finite element calculation software.
