Results of examination of experimental data on non-linear elasticity of rocks using experimentally determined pressure dependences of P- and S-wave velocities from various literature sources are presented. Overall, over 90 rock samples are conside

The microstructure-sensitive acoustic parameters (MSA parameters) of metal of the object under control are determined using measurements of the propagation time of bulk elastic waves of the ultrasonic range by the echo-pulse method. The structural fe

An acoustic method for nondestructive evaluation of variations in the metal structure caused by violations in manufacturing technology or by accumulation of damage during operation has been proposed. The method is based on measuring microstructure-se

We present the results of the studies of propagation of longitudinal acoustic waves in the media with a power-law hysteresis nonlinearity. Exact analytical solutions for the self-similar periodic waves propagating in such media without changing their

Models that adequately describe the effect of crack-like defects on the elastic moduli of solids are one of the key "ingredients" needed to obtain diagnostic conclusions about the structural features of the material. The change in the velocities of l

We study, both theoretically and numerically, propagation of the longitudinal elastic waves in the media with quadratically bimodular nonlinearity and viscous dissipation. Exact analytical solutions for simple and stationary waves are obtained and nu
