Re: [Question #549040]: Poison coefficient calibration

 

Question #549040 on Yade changed:

Luc Scholtès proposed the following answer:
The problem is that modifying this ratio will cause modification of
other macromechanical properties such as the strength... it might be a
non solvable problem in the end and this is actually a limitation of the
model that you use (JCFPM), but you have to make some compromises at
some point (like in any other modelling approaches).

Another thing: how is the lateral strain measured in your numerical
experiment? Is it a local measurement like in real experiments (strain
gauges) or is it through the displacement of the boundary walls? That
would actually be interesting to compare these two scales to make sure
you compare things that are comaprable.
