Abstract:
In this study, the ultrasonic wave generation and propagation were modeled
to simulate ultrasonic testing, using the photoelastic ultrasonic
visualization system. Ray-modeling is proposed for the modeling. In this
ray model, sound pressure field expressed as the density of rays. Each ray
branches at reflection or refraction by mode-conversion, and reflection or
refraction angles were obtained according to Snell's law. Variation of
sound pressure at reflection was determined using reflection coefficient.
Simulations of wave propagation and A-scan display were agreed with actual
visualization and ultrasonic testing results. This simulation is useful
for understanding the wave propagation in the specimen and A-scan display
in the ultrasonic flaw detector. F33,B13,H13,A25
