Thermal expansion and third order elastic constants of FCC metals

In this paper we develop the necessary expressions to evaluate third order elastic constants and temperature dependence of the thermal expansion of FCC metals. For this we use a previously proposed interatomic potential that can be expressed as a sum of two and three body force independent contribut...
