Their mechanical properties have a great effect on the automobile performance, especially on duration, vibration, noise and energy saving.
Many efforts [1-3] have been made to investigate their mechanical properties, deformation and failure behavior for improving the tire design and structural analysis.
Since the mechanical properties is related to the chemical structure, Fan et al.[4] assessed the effect of the crosslink structure on the dynamic mechanical properties of the natural rubber before and after aging at different thermal aging conditions.
Although numerous papers focused on the properties of rubber under different aging conditions, to our knowledge, little work is concerned with the mechanical properties of the aged cord-rubber composites.
The latter is also a major factor affecting the overall properties of the composites besides the constituent materials [7], while its effect is not taken into account in the classical theory of composites.

But, the reliability of thermal fatigue life may be lowered by the dispersion of design factors such as the dimensions, shapes, and material properties of package systems.
When design changes are done to improve reliability, the design factors which can be altered include the package dimensions and material properties.
Then, the design factors, which include the package dimensions and material properties, were evaluated in the full package model.
Table 2 Material Properties FEM Model and analytical condition Any change in the design factors of the package (e.g., dimensions, material properties) will affect the total equivalent inelastic strain range in the solder joints.
From Table 3, the factors which greatly affect the reliability of the solder joints are selected.

The microstructure of specimens was observed using TEM and the mechanical properties and wear resistance were examined.
To establish the optimum condition for each case depending on material, shape and required properties, etc., it is essential to manifest the precipitation mechanism and effect of each factors.
In this research, the effect of deep cryogenic treatment and tempering temperature on carbide evolution was investigated as a basic research on mechanical properties enhancement mechanism of the cryogenic treatment because the precipitation of carbide is affected by subsequent tempering temperature.
The hardness and the impact test were carried out to investigate the relationship between the microstructure and mechanical properties.
The mechanical properties of the sub-zero treated specimen and the cryogenic treated specimens are compared in the table 2.

Heat treatment is the main process to obtain desired mechanical properties and microstructure in this steel.
Because of the excellent combination of these properties, this steel has been accepted as a very useful engineering material [1,2].
The factors that affect on heat treatment are austenitizing temperature, austenitizing time and quenching rate.
Table 2 shows these factors and their level.

Based on the studying of the physical and mechanical properties of recycled coarse aggregate, the mechanical property of recycled aggregate concrete (RAC) with five concrete mixes with 0%, 25%, 50%, 75% and 100% RCA respectively are prepared.
The researches have shown that the mechanical property of RAC is mainly affected by the physical and chemical properties of the recycled coarse aggregate (RCA), the replacement ratio of RCA and the mixture ratio of the concrete [4].
It is known that the load carrying capacity and ductility of CFST columns is influenced by many factors such as the column diameter, the thickness of the steel tube, the compressive strength of concrete, the yield strength of the steel tube and the steel ratio [10,11].
The basic physical and mechanical properties of the RCA were studied because the physical and chemical properties of the recycled aggregate have distinct influence on the ultimate bearing capacity of RAC.
