.. index:: compute smd/plastic/strain/rate
compute smd/plastic/strain/rate command
=======================================
Syntax
""""""
.. parsed-literal::
compute ID group-ID smd/plastic/strain/rate
* ID, group-ID are documented in :doc:`compute <compute>` command
* smd/plastic/strain/rate = style name of this compute command
Examples
""""""""
.. parsed-literal::
compute 1 all smd/plastic/strain/rate
Description
"""""""""""
Define a computation that outputs the time rate of the equivalent
plastic strain. 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 in :doc:`units <units>` of one over time.
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.
