Results of theoretical researches of acoustic radiation energy interrelation with composition material deformation speed at its destruction by shear force with use von Mises criterion are considered. It is defined that to increase of deformation speed there is not a linear increase of acoustic radiation energy. Thus, increase of the acoustic emission signals maximum energy advances to increase of their total energy. It is shown that such increase of acoustic radiation energy is caused by increase of composition material process destruction speed. It is defined that the regularity of acoustic emission signals maximum and total energy change with increase deformation speed are well described by power functions.
