Modeling the Hardness and Mechanical Properties of Moulded Natural Rubber Pad Bryan B.
Nine ingredients of the rubber pad were chosen as factors and varied at two levels of proportions.
Through compounding, a rubber processor or manufacturer enhances the physical and mechanical properties of raw gum elastomer.
Regression coefficients of derived models for hardness and mechanical properties of moulded natural rubber pad.

The physical and mechanical properties along with their workability of concrete produced with RCA and ultra-fine fly ash were investigated.
In addition to environmental protection, conservation of natural resources, shortage of land for waste disposal, and increasing costs of waste treatment prior to disposal are the principal factors driving the recycling concept [1].
Different content ultra-fine fly ash is used to improve workability and mechanical properties of recycled concrete.
Furthermore, these mechanical properties are even improved at 28 days.

The change of steel mechanical properties is because of steel corrosion seriously.
Introduction Steel corrosion seriously affects its mechanical performance.
It is important to study the mechanical properties time-varying law of the corroded steel for the nondestructive testing and evaluation of the actual structures.
To sum up, few research has been studied the corroded steel mechanical properties changes.

Composites, with the combination of properties of component materials, are able to achieve the properties that none of the component materials has.
However, this kind of composite usually shows very poor mechanical behaviors in the corrosive environments due to the inherent poor anti-corrosion properties.
In this way the mechanical properties of the individual materials are fully exploited.
In addition, the adoption of pure aluminum thin film on the surfaces of the composite, which greatly improves its mechanical properties in the corrosive environments, also extends the application of organic polymeric composite to the bigger areas where good anti-corrosion properties are major concerns.

However, mechanical properties in conventional welding processes can vary due to factors like welding speed and feed rate [6].
The investigation aimed to understand the factors contributing to the significant variation in mechanical properties among these joints.
The analysis identified two main factors influencing the observed variations: geometric factors and metallurgical factors [17].
Understanding these factors is crucial for improving joint performance and ensuring desired mechanical properties [19].

Refining grain plays an important role in improving the mechanical properties of aluminum alloys.
The results show that the roller speed was an important parameters affecting the formability of the alloy.
Conclusions (1) A roller speed is an important factor affecting the ability of the fast-setting strip to form a belt.
Effects of Mg and Cu on microstructures and properties of spray-deposited Al-Zn-Mg-Cu alloys [J].

The results show that the main factors affecting the bearing capacity are steel pipe wall thickness, concrete strength, binding rebars in turn and the ductility is concrete strength, binding rebars, wall thickness.
Long or short rebars also significantly improve the deformation properties of specimens.
So the structure also can bring the mechanical property of concrete into play to maximum.
Once the constraint decreases, the mechanical properties of concrete itself will fully behave.
Influencing factors and level can been seen in table 2.

With very small volume fraction in the composite, nanoparticles are able to provide the composite material with strength and gas-barrier enhancements, without affecting other properties [1].
Since the filler weight ratio is very small, this occurs without affecting other favorable properties.
Results The models discussed in the previous section are analyzed here, to detect effects of different factors affecting the permeability of the nano-composite.
The interaction of the factors with the introduction of nano-fillers of different sizes is investigated.
The drastic reduction in permeability as the aspect ratio decreases is clear, without being affected by the other factors.

Effect of Heat Treatment on Microstructure and Mechanical Properties in ZK60 alloy sheet S.
Variations in microstructure and mechanical properties of ZK60 alloy sheets were investigated during T6 treatment.
Especially artificial aging after solution heat treatment affected both precipitates distribution and mechanical properties with aging treatment.
Variations of mechanical properties were related to precipitates, i.e. rod-shaped ( 1β') or disc shaped ( 2β') particles.
Tensile Properties Tensile test was carried out to evaluate the effect of solution treatment on mechanical properties.
