Scanning of acoustic emission signal by using waveguides
 Bančák, Matej ; Vlašic, František (referee) ; Mazal, Pavel (advisor)
Bachelor thesis is focused on the issue of scanning acoustic emissions from the surface of solid body and scanning with the help of acoustic waveguide placed on the solid body. The work includes the review of the present ways of scanning acoustic emissions, options of installation waveguide and propagation of waves. The practical part is focused on the experiment, which compares measured values from the surface of the test body and from the waveguide. The measurement was realized on steel of the standard quality for using a measuring instrument Dakel Xedo. The next object of this work was try to attenuate the reflected signal, which is produced by the action of force on the test body.
