Studies have shown that the existence of Bragg gaps is strongly connected with a large acoustic impedance ratio between the scattering and matrix materials.
Pipe A and pipe B are made up of different materials A and B, or different geometrical parameters, respectively.
The materials employed in the calculation are: steel as the material of pipe A and rubber as the material of pipe B.
The materials employed in the calculation are: steel as the material of pipe A and rubber as the material of pipe B.

It is therefore believed that materials with poseses dielectric and magnetic behavior would be the most potential candidates as absorbing materials.

After verifying the validity of numerical model, emphasis is on the influence of tension on propagation pressure considering isotropic hardening elastoplastic and elastic-perfectly plastic materials.
One should note that equation (2) is derived for SS304, thus only applicable for materials of similar hardening behavior.
Thus more caution is necessary during design of pipelines made of materials with little hardening.
This analysis may serve as a hint for more complex materials that anisotropy is of secondary importance.

But for some composite materials with poor thermal conductivity, it is not easy for them to achieve correct detection sometimes.
The physical parameters of the two materials were shown in Table 1.
