Rayleigh surface waves in assessing the state of metal structures

Abstract

The work is devoted to the search of a method of ultrasonic sounding for identification of the material state, permitting to refer the diagnosed structure to the class of structures, whose state is connected with the appearance of plastic deformations. The study has shown the application of surface Rayleigh waves allows to estimate the stress-strain state of metal structures in the field of both elastic and plastic deformation.
