In underground and slope engineering, a rock with cracks suffers from not only mode-I or mode-II loading, but also mode-III loading.
Therefore, investigation of the structural anti-plane problem is much significant for safety of engineering.
However, the analytical solutions are usually ineffective in the engineering structures with complicated geometry and loading conditons, where the numercal methods can be employed.

Introduction In order to improve the stealth and battle capability of the fighters as well as reach the flight standard of the civil aircraft, there is a requirement to reduce the noise radiation.
The theoretical model of sound absorption is established and the experimental investigation is conducted, which provide a theoretical and experimental reference to the engineering application in the fields of vibration reduction and sound absorption 1.
The research introduced in the paper can provide a theoretical and experimental base for the engineering application.
