Many factors can alter the mechanical properties of rubber.
Especially, because of the viscoelastic nature of rubber, their mechanical properties depend significantly on strain rate as well as temperature.
However, it is technically difficult to obtain accurate mechanical properties under the high strain rate loading conditions.
The SHPB technique has been continually modified to determine the dynamic properties of a variety of engineering materials such as metals, concrete, ceramic, polymeric and rubbers [2,3].
After the rubber specimens are heat-aged, physical and chemical properties are likely to be changed.

The wettability and mechanical properties of solder the joint of Sn-Cu-Ni-xSi3N4 had been investigated.
Nai in his study had reported that mechanical properties of both composites had majorly improved.
They reported that mechanical properties of the composite solder have improved significantly.
Overall, the addition of non-metallic particles can significantly enhance the mechanical properties as reported by several researcher [20-23].
The addition of reinforcement can act as nucleation in the molten solder, thus improving the mechanical properties.

Within manufacturing processes, the surface condition is characterized by geometrical aspects and by properties of superficial layers.
The properties of superficial layer analyzed in order to define the surface condition are the microstructure, the microhardness and the superficial residual stresses.
All these characteristics of surface layer could be affected by machining processes applied in order to obtain a certain mechanical part and, one the other hand, they strongly affect the service life of mechanical part.
In fact, the characteristics of the surface layer are properties taken into consideration when the quality of a certain product is evaluated.
In the future, there is the intention to obtain an improved classification of the machining processes on considering their common and distinct properties.

The electrical resistances and compressive strains of these cured nanocomposites under cyclic uploading/unloading were real-time collected, to explore their stress/strain-sensitive properties.
Luo et al. [4, 5], Li et al.[6, 7], and Yu et al.[8] have successively reported its good stress-sensitive function, besides its enhanced mechanical and vibration-damping properties.
Its main physical properties are listed in Table 1.
The auto data acquisition system setup for the piezoresistivity property of the cured nanocomposite was a similar schematic to our previous work [5].
As known, the main factors affecting the conductivity of composites are the contact resistance and the number of conductive netlike pathways [7].

It is therefore important to understand the effects of the environmental factors on the performance of these composites.
The effect of hybridization on mechanical properties of woven jute and glass fabric reinforced isothalic polyester composites has been evaluated experimentally by Ahmed et al. [5, 6].
Many studies have been carried out on the environmental effect on mechanical properties of composite materials [7, 8, 9, 10].
Tensile strengths and other properties of these materials have been determined [10] and they are given in Table 1.

The properties of the experimental soils are presented in Table 1, including mineralogy of X-ray Diffraction (XRD) analysis, the grain size distribution and other basic soil properties.
Dry clay soils and clay soil with non-polar fluids do not have plasticity properties [4].
These factors lead to the decrease in Atterberg limits.
The physical properties of the fluid such as viscosity would influence the liquid limit [5].
Although mechanical factors of soil not really changed, but a "pseudo-viscosity" caused by crude oil enhance plasticity and make flowing difficult, result decreasing in plastic limit, increasing in liquid limit, and the plasticity index increased corresponding.

Of course, cost factor should always be considered.
The Design Method The current structural design theory of civil engineering is based on the traditional materials of elastic properties and plastic properties.
Based on material micro mechanical design theory and technological reinforced cement mortar, thus greatly improved its ductility, and even called as concrete material of metal deformation.
So in compression parts(such as arch or dome), to instead steel with high-strength concrete, it’s not only save the costs, but also play their excellent mechanical properties.

Mechanical alloying.
A simplified analysis of the thermodynamics of the phenomena permits analysing the anti-friction properties of the alloys in terms of the activity coefficients of their constituents and indicates that during wear, a wear-resistant contact layer is formed which retards further damage.
To enhance the relatively poor corrosion properties of the Cu-Pb base alloy, a thin whitemetal (Pb 10Sn 2Cu, SAE 192) coating is applied electrolytically.
How tribolayer formation affects the resistance against adhesion can be understood by a simplified analysis.
Although it remains uncertain whether the contact zone is amorphous, it can be expected that its mechanical properties increase its wear resistance compared to the original surface, meaning that the specific composition of the alloy allows for the formation a wear resistant layer, which is renewed continuously as wear proceeds.

Based on the analysis of the main factors of work roll’s thermal behavior, the mathematical models are studied for predicting the work roll’s temperature distribution.
Meanwhile, the work roll’s temperature is affected by the deformation work and friction heat.
The resistance of deformation affects the friction heat and deformation work.
The value c1 depends on various factors including the roll velocity, interface conductance and temperature.
The heat flux generated due to the friction between the roll and the strip depends upon the normal pressure, the roughness of the surfaces in contact, and the properties of material.

Wear resistance is a structural-sensitive characteristic and depends on the size, shape, distribution and volume fraction of the solid phase, as well as on the mechanical properties of the solid and matrix phases.
Structural changes and related changes in mechanical properties, as well as surface roughness, affect the wear processes of steels [5, 6].
Changes in the relative wear resistance (a) and mass loss (b) of 18HN3MA-SH steel, depending on the exposure time of the EPA during experimentation of 10 and 20 minutes Abrasive wear is a complex process due to the influence of numerous factors on it, the main of which are the mechanical properties of the surface and abrasive, the normal load on the contact, the size and shape of abrasive particles, the speed of relative movement [13].
Summary Thus, it has been found that the main factors influencing the quality of the surface layer of steels during electrolytic-plasma processing are: heating temperature and holding time.
