The inhibitors always consist of relatively thin sheets of flexible materials.
With the development of computational science, to use the computational software to analysis this large scale problems such as the solid rocket motor’s working process being realized.
The results have high value for design the geometry and select the material of inhibitors.

So for some Large-size enterprises endeavor to process ethanol by non-corn materials, i.e. cornstalk.
But its materials could not be corn for the sake of the national grain security.

Fig.1 Failure Assessment Curves Fig.2 Schematic Diagram for Semielliptic for the materials Surface Cracks 1.2 Model Establishment for Cracks There are unavoidable defects existed in welded structures because of all kinds of factors, the surface defects and non-planar defects are included, among which the cracks are the most common but also the most dangerous form.
(3) It can be concluded from the security assessment result that the material used on underframe of the EMU aluminium car body is of excellent plastic performance but relatively short of toughness.

Because of the above reasons, to correctly understand the material characteristics of crashed layer and its comprehensive mechanical response with overlay will conduct the designer to design reasonable overlay and builder to make scientific treatment.
Model also use the pavement geometric parameters and material parameters after the second overlaying and the variation level of material modulus is 0.3,as shown in Tab.1.

.<~ DZ-Ni60AA powder is selected as test material, and put it into the incubator in 48 hours for heat preservation, drying processing before test in order to remove the adsorption moisture in the powder.
In addition ,grain refinementcan be eliminated interdendritic tensile stress, coupled with the uniform distribution of sintering layer, reduced the contraction stress between materials.
