On the site grouting test and compare the compressive strength of the stones of the body and the size of the diffusion radius, and compare the grouting materials with pure cement materials.
Through the comparative and analysis, the reasonable grouting materials are choosen.
Comparison analysis shows: The core compressive strength of pure cement materials and montmorillonite with cement mixing materials has little difference.

Introduction Functionally graded materials (FGMs) are known as materials in which a material composition varies gradually in some direction.
According to the knowledge of materials mechanics, the reason of the fracture of bending is that the maximum normal stress exceeds the ultimate stress of materials.
Fracture mechanics of functionally graded materials.

Nonlinear Constitutive Equation and Elastic Constant of Rubber Material Chen Li1, a, Li Zhao1, b 1Taiyuan University of Science and Technology, Taiyuan, Shanxi 030024, China; atydz_lc@126.com, bzhaoli061801@163.com Keywords: nonlinear; rubber material; constitutive equation; strain energy function; elastic constant Abstract.
Introduction Rubber materials research has a long history in the past 50 years.
People tried to make authentic description, but because of its characteristics of complex molecules and the dual non-linear of materials and geometry, and it is very sensitive to the impact of the temperature, the surrounding medium, strain over time, loading rate and the strain, these makes the establishment of a precise mathematical model more difficult.
The results In order to fully evaluate the strain energy function that we derived, we fitted the experimental data which come from Treloar’s work of rubber materials about three kinds of deformation modes (uniaxial tension, biaxial tension, pure shear), the result is satisfactory.

Here we discuss the main features of these materials.
These materials heat up when a magnetic field is applied.
Also the magnetocaloric performance of these materials is significantly better than the rare-earth based classical materials.

Friction and Wear Characteristics Cu-based P/M Brake Friction Materials with Addition of Fe and C 1,2,aR.J.
Introduction Powder metallurgy (P/M) friction materials are normally classified into three types; namely Cu-based, Fe-based and Cu-Fe-based materials [1].
Cu-based P/M friction materials were prepared and the effects of Fe and C friction components on the COF and wear behaviors of the materials were studied and discussed in this work.
