Development of acoustic methods and production of modern digital devices and technologies for ultrasonic non-destructive testing

Abstract

Acoustic fields, formed in solid half-space by small aperture sources of normal and tangent forces are investigated. Methods of ultrasonic testing, using transducers with dry point contact and electro-magnetic acoustic transducers are proposed. Results of investigated of multi-elements antenna are presented the examples of solving the specific tasks for testing the concrete structures, rails, welds and others a given. The information about the new up-to-date digital equipment, developed basing on information technologies is presented.
