Abstract: The multi-modes and disperse characteristics of guided circumferential waves in hollow cylinders is investigated by theoretical analysis and numerical computation. The geometrical factor that can affect the guided circumferential waves is confirmed. The relationship of guided waves between different hollow cylinders and relevant plate is found. Finally, the results indicate that some given guided circumferential waves are fit for non-destructive testing(NDT) of longitudinal cracks in hollow cylinders.
