Finnis-Sinclair potential (LAMMPS cubic hermite tabulation) for W developed by Ackland (2003) v005 |
---|---|
Description
A short description of the Model describing its key features including for example: type of model (pair potential, 3-body potential, EAM, etc.), modeled species (Ac, Ag, ..., Zr), intended purpose, origin, and so on.
|
Finnis-Sinclair model for tungsten designed for radiation damage. Built around early simulations using DFT on point defects in W, and thermodynamics. Correctly reproduces the DFT values for self interstitials which were unknown prior to 2002. Works well for radiation damage simulations. Never published, but available along with other less-well tested potentials in cubic spline form at http://www.homepages.ed.ac.uk/gja//moldy/AMISH.txt |
Species
The supported atomic species.

This bar chart plot shows the mono-atomic body-centered cubic (bcc) lattice constant predicted by the current model (shown in the unique color) compared with the predictions for all other models in the OpenKIM Repository that support the species. The vertical bars show the average and standard deviation (one sigma) bounds for all model predictions. Graphs are generated for each species supported by the model.

This graph shows the cohesive energy versus volume-per-atom for the current mode for four mono-atomic cubic phases (body-centered cubic (bcc), face-centered cubic (fcc), simple cubic (sc), and diamond). The curve with the lowest minimum is the ground state of the crystal if stable. (The crystal structure is enforced in these calculations, so the phase may not be stable.) Graphs are generated for each species supported by the model.
