WebThe EAM and EAM-based force fields are robust potentials with only modest demands for computational resources and their formulation is particularly well suited to model pure metals and alloys. EAM is empirically fit to the sublimation energy, equilibrium lattice constants, elastic constants, and vacancy and interstitial formation energies. WebJun 1, 2024 · The embedded atom method (EAM) [54] potential was used to describe the atomic interactions, based on our previous study that showed that this potential could accurately reproduce the mechanical and...

The atomic interaction in our simulation is based on the framework of embedded atomic method (EAM). It introduces multi-body interaction on the basis of pair potential, and can accurately solve the crystal elastic constant. WebAbstract: A set of parameters for the modified embedded atom method (MEAM) potential was developed to describe the perovskite silver tantalate (AgTaO3). First, MEAM parameters for AgO and TaO were determined based on the structural and elastic properties of the materials in a B1 reference structure predicted by density-functional theory (DFT). reihe opinie
