Re: [Question #665564]: EPWP (Excess pore water pressure)
Question #665564 on Yade changed:
https://answers.launchpad.net/yade/+question/665564
Jérôme Duriez proposed the following answer:
This being said, it is nevertheless possible for you to back-calculate
this excess pore water pressure "u" considering that
- triax.meanStress corresponds here to the mean effective stress p' from
actual experiments
- that u = p - p' where p is the mean total stress that would be
measured during experiments
- and accounting for the q-p relation pertaining to triaxial tests,
where q is the deviatoric total stress = q' the deviatoric effective
stress which you can directly measure in your model.
