| Summary: | (CW) Argon laser, was used to detect the waveforms. 150 to 90' at 15' intervals. Relationships were found based interferometry, accomplished with a constant wavelength between wave characteristics and the geometric aspects of essential to the non-destructive evaluation of these generation and detection techniques to investigate acoustic interrogating wave were used to identify parameters propagation of thermoelastically generated Lamb and Rayleigh waves in plates with ramp-like changes in section (12.86 mm). The angles of these ramps range from specimens. The experimental study was designed to examine the the plate. Changes in frequency spectra and phase of the The research described in this thesis uses broadband laser thickness. The structures to be studied consist of six thin (I mm) copper plates which ramp up into a thicker wave propagation in wedge type structures. The interrogating waves were generated by a Q-switched ND:YAG laser. Fizeau |
