FEP is a anisotropic material.
Many literatures confirm that FRP’s constitutional relationship is near perfect elastic material, so we think BFRP sheet’s constitutional relationship is linear.
It is a anisotropic material and it’s axial Poisson’s ratio is only 0.015~0.06 while concrete’s ratio is 0.1~0.2.

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.

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.
