Abstract : A microscopic viscosity approach is applied to the problem of attenuating elastic waves in solids having straight dislocations lying in energy wells biased by the applied shear stress. This model is found to be lacking. From analogy with ultrasonic attenuation, a more appropriate model based upon the loss mechanism applicable to the so-called Fatigue range of ultrasonics is proposed. The question of the shock front thickness associated with the decaying elastic wave is also touched upon. (Author)
