13 compute ID group-ID damage/atom :pre
15 ID, group-ID are documented in "compute"_compute.html command
16 damage/atom = style name of this compute command :ul
20 compute 1 all damage/atom :pre
24 Define a computation that calculates the per-atom damage for each atom
25 in a group. This is a quantity relevant for "Peridynamics
26 models"_pair_peri.html. See "this document"_PDF/PDLammps_overview.pdf
27 for an overview of LAMMPS commands for Peridynamics modeling.
29 The "damage" of a Peridymaics particles is based on the bond breakage
30 between the particle and its neighbors. If all the bonds are broken
31 the particle is considered to be fully damaged.
33 See the "PDLAMMPS user
34 guide"_http://www.sandia.gov/~mlparks/papers/PDLAMMPS.pdf for a formal
35 definition of "damage" and more details about Peridynamics as it is
36 implemented in LAMMPS.
38 This command can be used with all the Peridynamic pair styles.
40 The damage value will be 0.0 for atoms not in the specified compute
45 This compute calculates a per-atom vector, which can be accessed by
46 any command that uses per-atom values from a compute as input. See
47 "Section 6.15"_Section_howto.html#howto_15 for an overview of
48 LAMMPS output options.
50 The per-atom vector values are unitlesss numbers (damage) >= 0.0.
54 This compute is part of the PERI package. It is only enabled if
55 LAMMPS was built with that package. See the "Making
56 LAMMPS"_Section_start.html#start_3 section for more info.
