The influence of light illumination on the nonelastic properties of high-resistivity light-sensitive CdS crystals under ultrasound (the so-called photoacoustic effect (PAE)) is studied. It is shown that the crystal steady state is attained with two d

High amplitude ultrasonic vibrations with frequencies fr ∼ 90 kHz and vibration amplitudes e ⩽ 3.4. 10−4 were used to obtain oscillatory stresses σ ⩽ 14 MPa in CdS single crystals. Such treatment leads to the nucleation of cracks in annealed

The process of plastic deformation under the action of ultrasound differs in a number of ways from deformation under static loading; a computer simulation has shown that these differences are attributable to the specific characteristics of the operat
