Description

The elastic properties of copper-silver alloy were determined for different atomic compositions by molecular dynamics simulations using an embedded atom model (EAM) potential. The elastic constants (c${}_{11}$, c${}_{12}$, c${}_{44}$) that describe the Young’s modulus, bulk modulus, and shear modulus, were obtained from the stress-strain curves using strains applied at a constant rate. The temperature dependence of the elastic properties from 300K to 600K is also reported.
