WebEAM¶ Introduction¶. The Embedded Atom Method (EAM) [1] is a classical potential which is good for modelling metals, particularly fcc materials. Because it is an equiaxial potential the EAM does not model directional bonds well. However, the Angular Dependent Potential (ADP) [2] which is an extended version of EAM is able to model directional bonds and is … WebEmbedded atom method potentials.
