Thus, a very small section of the microstructure is actually being plastically deformed, so that a large portion of the materials is largely undeformed.
Once the onset of crack initiation takes place, the large pores will be linked, and the effective load bearing area of the materials locally will decrease very quickly, resulting in fracture of the material.

Barshinger [3,4] used the global matrix method to obtain dispersion curves of cylinder coated with a viscoelastic material.
It should be noted that there are two different materials in inner and outer shell, so the shell thickness has great influence on wave propagation in structures.

High level borehole of 3-219 was set in material roadway.
The horizontal distance between borehole bottom location and materials roadway was be controlled in the range of 5~23 m and the height from the roof will be controlled in the range of 15~25 m.
The specific laying route of pipeline: drilling field of 219 material roadway→219 material roadway→219 pump station→219 material roadway →Return airway of No 2 mining area→219 dedicated Release roadway for gas drainage.
