5. Meaning of internal variables#

The internal variables of the model at the Gauss points (keyword VARI_ELGA) are accessible by:

  1. \(\mathit{V1}\mathrm{=}{\varepsilon }_{\text{vp}}^{\text{11}}\)

  2. \(\mathit{V2}\mathrm{=}{\varepsilon }_{\text{vp}}^{\text{22}}\)

  3. \(\mathit{V3}\mathrm{=}{\varepsilon }_{\text{vp}}^{\text{33}}\)

  4. \(\mathit{V4}\mathrm{=}{\varepsilon }_{\text{vp}}^{\text{12}}\)

  5. \(\mathit{V5}\mathrm{=}{\varepsilon }_{\text{vp}}^{\text{13}}\)

  6. \(\mathit{V6}\mathrm{=}{\varepsilon }_{\text{vp}}^{\text{23}}\)

  7. \(\mathit{V7}\mathrm{=}p\), the cumulative plastic deformation

  8. \(\mathit{V8}\mathrm{=}r\), the viscoplastic isotropic work hardening variable

  9. \(\mathit{V9}\mathrm{=}D\), the damage variable

  10. \(\mathit{V10}\mathrm{=}\mathit{ind}\), indicator equal to 0 if the current point remained elastic at the current step, 1 otherwise.
