# compute smd/plastic/strain command

## Syntax

    compute ID group-ID smd/plastic/strain

- ID, group-ID are documented in compute command

- smd/plastic/strain = style name of this compute command

## Examples

    compute 1 all smd/plastic/strain

## 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 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 the Howto output page for an overview of LAMMPS output options.

The per-particle values will be given dimensionless. See units.

## Restrictions

This compute is part of the MACHDYN package. It is only enabled if LAMMPS was built with that package. See the Build package page for more info. This compute can only be used for particles which interact via the updated Lagrangian or total Lagrangian SPH pair styles.
