New question #687413 on Yade:
https://answers.launchpad.net/yade/+question/687413

Hello,

I know that the stress-strain curve of a cylinder made of spheres in Yade depends on the packing of aggregates. I have tried making cylinders with different packing using makeCloud function with seed=1, 2, 3 and then compress the particles to a specific porosity. Although all cylinders have same porosity and approximately same number of particles, for each cylinder the stress-strain curve is drastically different. 

My question is, is there a function, equation or a method to quantify the packing arrangement of spheres to explain the effect of packing on the mechanical properties of a cylinder made of particles? 

>From a previous question [1] I learned that I can show the network of interactions and hide the spheres for different packing arrangements, but it would be great if there is a parameter or an equation that differentiate different packing arrangements. 

I hope my question is clear and I appreciate any suggestions or thoughts in this regard. 

Thank you,
Othman
