There are numerous methods of the technical diagnostics that allow controlling conditions of material or construction. One of such promising methods is the method of measuring Rayleigh waves. The effectiveness of this method based on the fact that acoustic waves used in it are related to the structure of material, and characteristics of the structure change when material defects are appearing. Moreover, such a method allows distinguishing among strains of 1st (macro) and 2nd (micro) types due to the changes occurring in the speed of ultrasound depending on the loading level. The result shows that such a method can became an effective diagnostic tool of non-destructive control for materials.
