From the aspect of sample size of mathematical modeling, we chose four factors.
Then we got 14 model factors including six kinds of possible interaction and four kinds of possible acceleration.
But the crumb rubber plastic concrete is a kind of composite material, the interaction of different factors must affect the concrete performance consequently, we must consider all of the influencing factors to make our work have more research significance.
The mechanical analysis of effect of the main influencing factors to crumb rubber plastic concrete elastic modulus (1)cement is the main active ingredient of concrete.
Because the plastic concrete is a kind of hererogeneous multi-phase material, the density and the volume percentage of its component and the transition zone properties determine its flexibility characteristic.

Strain measurement from the strain gauge is partially affected by carrier and adhesive materials and their thickness.
Younis et al. [4] studied the strain gauge backing effects on measuring steep strain gradient and the principal sources of error that influence the measurement of stress concentration factors.
Mechanical Characterization of Adhesives There are wide ranges of test methods available to evaluate the performance of adhesives.
In the present work, the mechanical properties of adhesives were obtained from testing bulk adhesive specimens, as they give more accurate results than adhesive bonded joints.
Conclusion Adhesive material properties were obtained from tension test on bulk adhesive specimen.

It was shown that superplastic elongation for such alloys depended on some microstructural properties including shape and size of the grains, phase composition and distribution of the phases in the microstructure.
These results suggest that the achieved elongation in superplastic materials is not only dependent on the grain size and there should be other factors affecting the superplastic elongation.
Besides the F/UFG microstructure, phase composition can also be proposed to be an important parameter affecting the achieved superplastic elongation.

The percentage of recrystallized grains of the alloy is found to be affected by dispersoid distribution.
Small additions of zirconium can often improve the properties of high strength aluminum alloys by forming metastable, coherent Al3Zr dispersoids, which have a strong influence on recrystallization, grain size and mechanical properties of wrought aluminum alloys [5-7].
During homogenization, there are two main factors influencing the precipitation of dispersoids, the supersaturation of the solid solution and the diffusivity of the solute in the matrix respectively [7].
Earlier research shows that the precipitation behavior of Al3Zr particles is affected by the heating rates during homogenization treatment [10, 13].

Within this study factors influencing the specimen temperature during tensile loading and unloading are experimentally analyzed to improve the determination approach and the understanding of it.
The extent to which the temperature behavior really reflects the material behavior must be investigated in detail in order to exclude the possibility that external factors such as the measurement technique or the laboratory conditions influence the result.
The main mechanical material properties are summarized in Table 1.

However, the evaluation range for YS0 is not affected, so that this also has no influence on the parameter.

The barrier and conformal properties were achieved by using the inherent mechanical flexibility and hydrophobic properties of PDMS [19, 20].
The mode mixity is a function of the stress intensity factors, KI and KII, and, which is a material property parameter given in [24].
These techniques bear the potential for engineering barrier properties by utilizing the permeability of polymers in a positive way.

Microstructures, tensile properties and work hardening behavior of friction stir welded (FSWed) AA2219-T62 aluminum alloy (in its one-third bottom slice of a 20 mm thick plate) were evaluated at different strain rates.
The main changes in the tensile properties of the welds were explained via the differences in the strain-hardening behavior which controlled the strength and resistance to plastic localization.
More recently, Chowdhury et al. [10,11] examined the effect of pin tool thread orientation and weld pitch on the tensile properties and strain-hardening behavior of FSWed AZ31B-H24 Mg alloy.

There are some various advantages of activated carbon, such as excellent adsorption ability, good catalytic properties, fine chemical stability, high mechanical strength, heat-resistant, so it is widely used in the fields of food processing, chemical, medicine, military and so on.
Single factor experiments and orthogonal test are adopted to study the impact of activation parameters on the activation effect.
Single factor experiment results Impact of activation temperature on the iodine value.
Results of orthogonal experiment According to the single-factor experiment results, the activation temperature, impregnation ratio and activator concentration were selected as the three main factors affecting activation effect, and three levels of orthogonal experiment to determine the cross influence of various factors on the activation effect.

Surface property, especially hydrophilicity, is considered to have a strong influence on the biological reactions.
That is to say that super-hydrophilic valve metals without coating of bioactive substances had high osteoconductivity, and the surface properties strongly affected on the osteoconductivity.
Introduction There are several factors that used to select materials for different components in biomedical devices, such as: the materials must have an excellent biocompatibility, show an excellent corrosion resistance and appropriate mechanical properties (low modulus elasticity) [1].
Surface roughness and hydrophilicity are important factors of biomaterials which related with protein adsorption and cell adhesion after implantation into the body [8-11].
Surface properties especially hidrophilicity contribute strongly affect on osteoconductivity of valve metals.
