Modelling and evaluating multiple constituent alloys in LAMMPS

Submitted by Surendran M on

I have the following questions.

  1. How to model alloy in LAMMPS? How to automatically randomize the position of atoms of various types?
  2. Also how to evaluate the mechanical properties such as Elastic modulus and Fracture toughness?
  3. Is it possible to model interface fracture using LAMMPS?
