"Evolutionary" is an interesting word! :)
Yes, I insist on defining the rate of loading, which is more important 
that the final state for materials like ours, whose behaviour is rate 
dependant and path dependant.
And in fact the rate of loading is what you'll find in Thornton and 
Cundall when defining the relative velocity across periods, it is my 
best bet before reading the papers.
There are high probabilties that we are heading toward the same 
algorithm as them, which is probably the same as in molecular dynamics 
litterature (modulo notations, sign conventions, namings, etc.), since 
we all have the same maths.
