The simulation results based on the different rubber materials reveal that the selection of the shape of the cavity depends on the material characteristic.
The materials include the Chlorosulfonated polyethylene rubber and steel, and the perforation coefficient is 0.2 , 0.3 , 0.4 respectively.
As shown in Fig.7, the difference between materials leads directly the difference between the cavity structures.

Regardless of the size of these flaws, they can reduce the strength of rock materials [1].
Transparent brittle materials are able to solve this problem.
Material selection This paper chooses PMMA and glass as the test materials.
This method applies to materials which can be liquefied such as glass and resin.
It must be cautious to generalize the result to rock materials.
