Strain calculations in lammps


I want to do strain calculations for 100 surface of Au nanoparticles in lammps. I have searched in the lammps forum but did not get a helpful answer. I also tried to search on google and lammps manual but did not get much help, Perhaps because I am new user of lammps.

Can you please guide, should I use fix deform command for this? or there is another way? I am sorry it is very basic question but I would really apperciate your suggestions/help.


Best Regards,


I think that you need to search “Uniaxial Tension Lammps” on google, then you can find the ICME site for the stress-strain simulation.

You may need to change the lammps input file for your purpose.
