The vehicle technology includes the use of lightweight materials such as aluminum, magnesium, high quality steel and composite materials, and the optimum design, which make car own quality reduce 30% ~ 50%.
The high pressure radial tire made of special material can reduce 50% of the rolling resistance and the streamlining of body especially the underbody can decrease air resistance by 50% and so on.

When the temperature rise is higher, the influences of material properties depression and temperature stress will be superimposed.
The material is Q235 steel, and the maximum displacement will be calculated when the temperature rises from 20 ˚C to 550 ˚C.

It can be seen that，when λ greater than 0 less than 0.5,the rubber material is only affected by shearing action, and always have rolling action.
When λ greater than 0.5 less than 1, the rubber material is affected combination of shearing action and stretching action.
The rubber material in the process of open mill mixing, various forces and speed of the axis direction are same.
Therefore, the model of open mill mixing process can be simplified to two- dimensional model of the rubber material (the axial section )

But for saving material, the gearlike cylindrical structure of bearing, which is shown in Fig.2, is adopted [2].
Then in grinding process, plastic deformation takes place in the outside layer material of workpiece.
of bearing, µ - Poisson modulus of material of bearing.

For optimization, the bridge is constructed as a hybrid system, with different materials used for main and side spans to balance the forces induced on both sides.
Namely, the side span of the bridge was built using heavier, concrete-based materials, and the main span using lighter, steel-based materials.

Axial compression, the initial testing machine is the work done by the energy dissipation of the rock material.
From this may know, is in peak strength of rock after absorbing energy is mainly used to internal material plastic sliding between doing work.
Summary The destruction of the rock material and energy is closely related to the changes, especially in the high ground stress conditions.
