calculating load by the indenter

LAMMPS LAMMPS Mailing List Mirror

In the indentation simulation, one of the common practices is plotting the load-displacement curve.

Where, load is Force/area.

I am using spherical indenter with the “fix ID Group-ID indent K sphere values…”

Is there any LAMMPS command (e.g. any FIX or COMPUTE ) to calculate the load by the indenter ?

Regards.

have you read the documentation? is says:

This fix computes a global scalar energy and a global 3-vector of
forces (on the indenter), which can be accessed by various output
commands.

the rest can be done in post-processing.
