Anelastic Relaxation Due to Interacting Point Defects

The anelastic relaxation is one type of mechanical response of solids in which, on applying a stress, besides the instantaneous elastic response according to Hook’s law, a retarded strain is found [1]; it is the mechanical analogue of the dielectric relaxation. However, whilst some work has been done in order to see the effect of the random interactions between dipolar impurities on dielectric relaxation, little has been done in this direction for anelastic relaxation.
