compute stress

LAMMPS LAMMPS Mailing List Mirror

Dear All,

I do not know if LAMMPS can include a command to compute Lutsko stress, which is a local stress that considers the fraction of the bond length near the boundary of your specified region. This type of stress is useful to analyze inhomogeneous solid material. If not, could any one let me know where I can modify the code to include it. Many thanks.

Best,
Mengyu

I've never heard of this kind of stress and LAMMPS doesn't
have it. But you can add a new "compute" to calculate whatever
you wish. You can also look at the fix ATC package which computes
Hardy stress among other quantities.
