In this work we model the oscillations of an elastic body. Our aim is to achieve the phonon spectra of a sphere. Once we achieved this goal we develop different codes in order to see the behavior of phonons' frequencies with the radius. Later on we study numerically the thermal excitation of this phonons system.
