That means the material removal can be controlled by selective deliquescence on the convex.
Consequently, the material removal ratio is directly proportional to pressure and fluid flow, as shown in Fig. 3 and Fig. 4.

The stress concentration due to the materials with different mechanical properties makes the most damage occurred in the component interface.
Rubber fault is caused by material inside or pre-existing or introduced small defects in surface.
Considering impact on the interface crack caused by large deformation of material, we choose the relatively simple Mooney-Rivlin constitutive model which can represent large deformation capacity to simulate the rubber material, determine that the Shore hardness HA is 66 degrees by the rubber hardness test, and propose that material constant C10 is 0.6182, C01 is 0.1546.

Introduction Composite materials have been widely used as light-weight automotive and aerospace structural members.
For finite element analysis (FEA), a progressive damage evolution model has been studied to analyze the failure of composites materials [2].

The results demonstrate that the maximum predicted temperature using the standard flame settings exceeds the required temperature for evaluation of a fire-resistive material.
It is therefore essential to characterize the thermal parameters of the standard flame adequately to allow proper evaluation of a fire-resistive material.
