Description
|
|
"""""""""""
|
|
|
|
Define a computation that outputs the equivalent plastic strain per
|
|
particle. This command is only meaningful if a material model with
|
|
plasticity is defined.
|
|
|
|
See `this PDF guide <USER/smd/SMD_LAMMPS_userguide.pdf>`_ to use Smooth
|
|
Mach Dynamics in LAMMPS.
|
|
|
|
**Output Info:**
|
|
|
|
This compute calculates a per-particle vector, which can be accessed
|
|
by any command that uses per-particle values from a compute as input.
|
|
See :ref:`How-to discussions, section 6.15 <howto_15>` for
|
|
an overview of LAMMPS output options.
|
|
|
|
The per-particle values will be given dimensionless. See :doc:`units <units>`.
|
|
|
|
Restrictions
|
|
""""""""""""
|
|
|
|
|
|
This compute is part of the USER-SMD package. It is only enabled if
|
|
LAMMPS was built with that package. See the :ref:`Making LAMMPS <start_3>` section for more info. This compute
|
|
can only be used for particles which interact via the updated
|
|
Lagrangian or total Lagrangian SPH pair styles.
