Abstract
Nonlinear elastic characteristics of metal are connected both to development of microdamage and with change crystalline's structures of materials. These both processes simultaneously occur at plastic deformation and destruction of metal alloys. In article research results of influence of plastic deformation on acoustoelastic coefficients of steel 30 have been shown. High correlation between acoustoelastic constant and parameter of acoustic anisotropy was found. Taking this connection into account allows one to increase accuracy of measurement of stress by the acoustic method.
