The atomic-level stress has been mentioned in many papers (eg. works of Diao JK and Cao AJ). I think the definition of the atom volume is the most crucial.
So I wonder to know how to calculate the effective volume of the atom, which is said difficult in the lammps manual. Does the Voronoi volume make sense?
Is it possible to finish this work by using lammps? Or some other alternative methods?
Any suggestions will be appreciated!
