Sandwich structure is an attractive structural design concept by a proper choice of material; it can produce strong and light materials.
Skin must be selected from high strength materials and core from low strength materials, but its higher thickness provides strong and light materials will be produced [10].

Pile is assumed to be completely linear-elastic material.
Soil materials are granular materials, compressive yield strength is much greater than its tensile yield strength, and material shear, the particles will expand.
Because of the in-situ analysis and test of pile-soil interaction costs human and material resources in huge, so it’s extremely difficult to do in-situ analysis of pile-soil interaction.

Introduction Product quality is the accumulated and combined result of machine, equipment, personnel, environment, material and other elements.
DV, WS, MT, PS, EV are used to represent equipment, workmanship, material, personnel and environment.
Equipment has many attributes such as type attribute, working capacity attribute and state attribute, which can be represented by DVT, DVC, DVS; method can be described by WST,WSI,WSP which present the resources type attribute technological process information attribute and parameter attribute respectively; material includes material type attribute. material performance attribute and material state attribute which are denoted as MTT,MTP,MTS; the factor of personnel consist of type attribute ability attribute and status attribute and these attributes can be represented by PST,PSA,PSS; environment has its basic attribute —EVP.

The 3-D model is shown in Figure 1.The material properties for the copper wire bond, bond pad and die are shown in Table1.
The material properties of the shear ram is set to an extent with its Young’s modulus substantial large when compared to other materials in this modeling making the shear tool behaves as a rigid body.
Higher shear height will produce less deformation as the material will have higher resistance to plastic deformation at higher height.

Theoretical model is about a single abrasive cutting edge removing material Belt grinding process includes many different shapes of cutting edge grinding the workpiece surface, so applied theoretical model (which helps to explain the abrasive and material surface about the removal process and interaction mechanism) is about a single abrasive cutting edge removing material [3].
When the machined material is determined, if Vickers hardness of material changing is not considered in the process of grinding, Vickers hardness is a certain value.

In view of the austere problem that we have to resolved, there has been an increase in research activities targeted at improving the flame ability and thermal stability of materials and more attention had been paid to IFR which is widely used as halogen-free additives in some polymers, rubber and so on, during to its advantages of little smoke and low toxicity [2].
Experimental Materials.
It was widely used to evaluate the flame retardant properties of materials by UL-94 vertical burning tests and LOI measurements.

In nature, it is a kind of planning and management of human production activities with the least consumption of materials and energy, which minimizes waste, changes waste into resources, converts waste into harmless waste, or eliminates waste in the production process.”
Materials used for filling are broken coal gangue, fly ash, special binding agent, water, etc.
The use of existing gangue and fly ash in the coal mine as filling materials makes the filling cost significantly reduced and achieve the new idea of green mining technology of “exchanging gangue for coal”.
