Dear all,

I am still investigating the cohesionlessMomentRotation.
It is written in the sources files that this code has been "verified 
with the paper of Plassiard in GM".

However, Plassiard considers in his paper "and in his thesis" only the 
rolling part of the relative rotation of particles (and thus only 
bending moment), whereas in the code rolling and twist part of the 
relative rotation are considered (and thus bending and twist moment).

My question: is there a particular reason for that? What is the 
motivation of the person who wrote this code? I don't say that is bad or 
good, but I would like to have an idea about advantages and 
disavantages, and physical meaning for considering a twist moment.

Jean-Patrick, if you read this mail, please give your opinion!

Best regards,
Luc
