    Status: Open => Needs information

Jan Stránský requested more information:
Hello,

> TriaxialStressControl

TriaxialStressController?

> the anisotropic consolidation

please be more specific:
- what is the condition/load for the third direction? strain (rate)? stress? what value?
- what is time propagation of the values? just sigma1/sigma3 is constant? or should sigma1 evolve somehow, like linear growth?

> it seems that TriaxialStressControl uses the strain increment to
compress sample

Try to avoid "it seems", or at least provide information why it seems so
(try to make some evidence, provide reference, MWE [1], ...)

TriaxialStressController (and similar engines) indeed uses exclusively strain (rate) to load the sample.
However, you can apply strain (rate), such that the resulting stress matches the prescribed value. This way, you can "impose stress", although indirectly.

Cheers
Jan
