Sumario:The purpose of this work is the simulation by molecular dynamics of disordered atomic systems, in particular metallic glasses. Metallic glasses are produced by fast solidification of a metallic alloy, and they show interesting mechanic properties. Aeronautics is one of the proposed fields of application of metallic glasses, provided that the present limitations in their production process are overcame. Molecular dynamics simulation allows one to reproduce the production process, to analyze the resulting atomic structure, and to study the atomic dynamics of the materials both in the liquid and glass state. In this work the phononic spectrum of metallic glasses, ultimately responsible of the brittle fracture, was studied.
