record deformed shape in cohesive triaxil test

Hello,

Are you asking us about how to record the strain of a specimen being triaxially compressed by TriaxialStressController() [1]?

If your TriaxialStressController is labeled "triax":

e11, e22, e33 = triax.strain[0], triax.strain[1], triax.strain[2]

If you are more interested in the physical dimensions of the sample, rather than the strain:

width, depth, height = triax.width, triax.depth, triax.height

Hi Robert,

thanks for reply and sorry for not being specific.

I meant tracking the force chains in cohesive triaxial tests - Visual observation in 3d Sample

Thanks,

Also, if you search this forum for "force chain" you will find several other answered questions describing how to visualize force chains.

Cheers,

Robert

Do you mean the force network instead? (force network: serie of lines presenting all interactions, and lines' thickness represent force's magnitude?) Be careful to use the terminology 'force-chain'.

If so, you can do it outside of YADE, try saving interactions info data and plot it with matplotlib or mayavi.
Or you can do it the simple way: save YADE model (yade.gz for example) and you can access this every via YADE UI.
Load the saved model, then in the UI window, do this:
Display Tab -> OpenGLRenderer -> tick 'intrPhys'
You can also hide spheres by unticking 'shape'

Good luck

Hi Robert,

Thanks for your time and recommendation.

Hi Hien,

thanks for recommendation. I meant force network.
