Harmonic force field of a system of bound atoms

On the example of a simple mechanical model (a linear chain of three bound atoms) it is shown that the equilibrium conditions of forces and force moments completely determine the linearly elastic properties of the structure and make it possible to find the number of free parameters of the quadratic...
