distance*|F|=work (|F| is already known, it is radius of
plasticzone for
given sigmaN)? If you do cross product, then you have to compute the
norm of it anyway.
Is the distance to compute energy you are talking about a total or an
incremental one?
We refer to increments, always, even in the so called "total" formulation. Increments rule the world. ;-)
