In the present article, the phonon dynamics of Pd39Ni10Cu30P21 bulk metallic glass (BMG) using Show’s optimized model pseudopotential at room temperature are reported. The theoretical effective atom model (EAM) with Wills-Harrison (WH) approach are utilized for the computation of the interatomic pair potential (PP) and pair correlation function (PCF), respectively. Also, the phonon dispersion curves and their related static and thermodynamic properties are computed through Takeno-Goda (TG) model. The screening dependency on the aforesaid properties are studied by using different forms of the local field correction functions.
