Meaning of internal variables
====================================

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


1. :math:`\mathit{V1}\mathrm{=}{\varepsilon }_{\text{vp}}^{\text{11}}`


2. :math:`\mathit{V2}\mathrm{=}{\varepsilon }_{\text{vp}}^{\text{22}}`


3. :math:`\mathit{V3}\mathrm{=}{\varepsilon }_{\text{vp}}^{\text{33}}`


4. :math:`\mathit{V4}\mathrm{=}{\varepsilon }_{\text{vp}}^{\text{12}}`


5. :math:`\mathit{V5}\mathrm{=}{\varepsilon }_{\text{vp}}^{\text{13}}`


6. :math:`\mathit{V6}\mathrm{=}{\varepsilon }_{\text{vp}}^{\text{23}}`


7. :math:`\mathit{V7}\mathrm{=}p`, the cumulative plastic deformation


8. :math:`\mathit{V8}\mathrm{=}r`, the viscoplastic isotropic work hardening variable


9. :math:`\mathit{V9}\mathrm{=}D`, the damage variable


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