compute plasticity/atom command :h3
[Syntax:]
compute ID group-ID plasticity/atom :pre
ID, group-ID are documented in compute command
plasticity/atom = style name of this compute command :ul
[Examples:]
compute 1 all plasticity/atom :pre
[Description:]
Define a computation that calculates the per-atom plasticity for each
atom in a group. This is a quantity relevant for "Peridynamics
models"_pair_peri.html. See "this document"_PDF/PDLammps_overview.pdf
for an overview of LAMMPS commands for Peridynamics modeling.
The plasticity for a Peridynamic particle is the so-called consistency
parameter (lambda). For elastic deformation lambda = 0, otherwise
lambda > 0 for plastic deformation. For details, see
"(Mitchell)"_#Mitchell and the PDF doc included in the LAMMPS
distro in "doc/PDF/PDLammps_EPS.pdf"_PDF/PDLammps_EPS.pdf.
This command can be invoked for one of the Peridynamic "pair
styles"_pair_peri.html: peri/eps.
The plasticity value will be 0.0 for atoms not in the specified
compute group.
[Output info:]
This compute calculates a per-atom vector, which can be accessed by
any command that uses per-atom values from a compute as input. See
Section_howto 15 for an overview of LAMMPS output options.
The per-atom vector values are unitlesss numbers (lambda) >= 0.0.
[Restrictions:]
This compute is part of the PERI package. It is only enabled if
LAMMPS was built with that package. See the "Making
LAMMPS"_Section_start.html#start_3 section for more info.
[Related commands:]
"compute damage"_compute_damage.html, "compute
dilatation"_compute_dilatation.html
[Default:] none
