WebApr 25, 2006 · Abstract. We propose an extended Finnis–Sinclair (FS) potential by extending the repulsive term into a sextic polynomial for enhancing the repulsive interaction and adding a quartic term to describe the electronic density function. It turns out that for bcc metals the proposed potential not only overcomes the 'soft' behaviour of the original ...

WebSep 11, 2015 · MD simulations are carried out using LAMMPS software and the Finnis–Sinclair interatomic potential developed by Wilson and Mendelev is used to describe the interatomic interactions. It is observed that addition of small amount of impurity (0.1 % Zr) increases the interface growth velocity of pure Ni during solidification. … In computational chemistry and computational physics, the embedded atom model, embedded-atom method or EAM, is an approximation describing the energy between atoms and is a type of interatomic potential. The energy is a function of a sum of functions of the separation between an atom and its neighbors. In the original model, by Murray Daw and Mike Baskes, the latter functions represent the electron density. The EAM is related to the second moment approximati… form up-1c https://prestigeplasmacutting.com
