3.2. Characteristics of the mesh#

Number of knots: 8

Number of meshes and type: 1 HEXA8

3.3. Tested values#

The components \(\mathit{xx}\) and \(\mathit{zz}\) of the stress field SIGM_ELNO, and the cumulative plastic deformation under tension (second internal variable, second component of the field VARI_ELNO) were tested. Since the displacement is imposed, field EPSI_ELNO is not tested.

The three moments correspond to a displacement of \(0.005\), \(0.01\) and \(0.015\mathit{mm}\).
