<h2>
Description
</h2>
<p>
Define a computation that outputs the equivalent plastic strain per
particle. This command is only meaningful if a material model with
plasticity is defined.
</p>
<p>
See
<a
class=
"reference external"
href=
"USER/smd/SMD_LAMMPS_userguide.pdf"
>
this PDF guide
</a>
to use Smooth
Mach Dynamics in LAMMPS.
</p>
<p><strong>
Output Info:
</strong></p>
<p>
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
<a
class=
"reference internal"
href=
"Section_howto.html#howto-15"
><span
class=
"std std-ref"
>
How-to discussions, section 6.15
</span></a>
for
an overview of LAMMPS output options.
</p>
<p>
The per-particle values will be given dimensionless. See

<h2>
Restrictions
</h2>
<p>
This compute is part of the USER-SMD package. It is only enabled if
LAMMPS was built with that package. See the
<span
class=
"xref std std-ref"
>
Making LAMMPS
</span>
section for more info. This compute
can only be used for particles which interact via the updated
Lagrangian or total Lagrangian SPH pair styles.
