Title: AMPLITUDE-DEPENDENT ULTRASOUND ATTENUATION DUE TO INCLINED DISLOCATIONS
Authors: Julia M.Khalack (Bogolubov Institute for Theoretical Physics of the Ukrainian National Academy of Sciences, 14b Metrologichna St., 252143 Kyiv-143, Ukraine)

Amplitude dependence of the ultrasound attenuation and change of the elastic modulus due to the dislocations with a certain number of the geometrical kinks at zero temperature is investigated by the numerical simulation of dislocation motion. A decrease of attenuation before the amplitude of stress in a slip plane achieves the Peierls stress value is found.
