We give a continual model of an elastic medium with a field of distributed defects, and use it to study the frequency transformation effect in elastic waves. By an example of numerical simulation of one-dimensional waves arising under a harmonic action on a layer with defects we demonstrate the possibility of describing frequency transformation in the framework of the model.
Keywords: elastic waves, frequency transformation, field of distributed defects.
