If you mean the law described e.g. in 
http://geology.msu.edu/pdf/Poisons_S_vel.pdf (2), it means computing
contact stiffnesses from bodies' rigidities differently and updating
them based on the (varying) confining force. Quite easy to do, and
certainly a welcome addition to yade (we are here to help you with
that).

There is ThreeDTriaxialEngine by Luc Sibille; Bruno/Luc will tell you
how to use it.

TriaxialTest can use particle growth for compaction, you can certainly
do the same.
