Hi Vincent,
I didn't see the need to find a reference for contour integral of Cauchy
stress, since it is something classical in continuum mechanics courses.
The demonstration is in function's documentation.
I don't understand this in your paper :
At this scale, a Cauchy stress in the sense of

One might wonder how it is possible to compress the sand isotropically

You're right! Some people consider granular matter as a continuous
media. I don't.
The integral is for one grain alone. Considering one grain as a
continuum doesn't sound so absurd, does it?
We are far

We are far above the atomic scale.
As I said, I see no problem for the computation. I just made a
Hi,
Have a look to this paper: http://www.springerlink.com/content/l133vr26m7142101/
I can send you the pdf if necessary.
The stress computation at particle level is explained in section 5. Basically,
it correspond from the dimensional point of view to the moment tensor divided
by a volume. The

No worries. I didn't plan to remove anything.
I noticed the other ones didn't have python wrapping, that's why I
simply named the python function bodyStressTensors.
It can be adapted later

I've been adding another definition of stress in
