[Description:]
|
|
|
|
|
|
|
|
|
|
Define a computation that calculates the per-atom plasticity for each
|
|
|
|
|
atom in a group. This is a quantity relevant for "Peridynamics

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.
