Keywords:ultrasonic non-destructive testing, surface waves, creeping waves, whispering gallery effect
AbstractThe properties of longitudinal surface acoustic waves (LSAW) (creeping waves) when they are propagating on the cylindrical convex surface are experimentally analyzed in this research. The analysis was done with the physical seismic shock wave model from duralumin. It was experimentally observed that LSAW are the fastest propagated acoustic waves with the speed and especially strength increasing when they are propagating on the cylindrical convex surface. LSAW are the specific whispering gallery effect manifestation form in the solid.
