I read a message about the discussion of “calculating Young’s modulus” between you and Steve and other lammps users from Google search.
Because I joined the lammps mailing list is late (11/02/2009) I could not get this message in my mailbox.
Now I also begin to do the Young’s modulus calculation, I’m not clear about the definition of stree. I want to use the stress-strain curve to determine the Young’s modulus. If I use an external force to tensile the boundary atoms, then the stress should be defined as the external force dividing the cross section area or the calculated stress in the tensile direction in lammps (including the interatomic interaction and the kinetic energy contribution)? I think you should finish the Young’s modulus calcuation of Al using lammps, can you show your lammps input script here? Thanks so much!
In addition, can anybody tell me there is a way to receive all mails from the lammps mailing list prior to my registration time?
