Residual stresses generated in milling process affect the performance of machined components.
The chemical composition and the mechanical properties of the material are presented in Table 1 and Table 2, respectively.
In the cutting speed region from 300~1500mm/min, the dominative factor which affects the surface residual stress is changing due to the temperature increasing, that is, from the mechanical loading in the low speed cutting to the thermal loading in higher cutting speed.
(2) The dominative factor affects surface residual stresses is changing from the mechanical loading to thermal during the cutting speed range 300~1500mm/min.
(4) The observed residual stresses values show that the residual stresses in both the feed direction and the normal direction are generated in the milling process and their properties and values are almost the same.

Welding involves a rapid change in the temperature which alters the microstructure and the mechanical properties of the steel.
Understanding the influence of welding conditions on the mechanical properties of DP 600 is useful for both the automotive industry and steel producers.
The process comparison shows differences in the final mechanical properties resulting from the microstructural differences in the welding zones.
The first two factors are influenced by welding process parameters and governed by the net heat input and power density distribution.
Mechanical testing results The differences in the weld microstructures affect the mechanical properties of the dual phase steel, as shown in table 3.

Grain size influences casting quality and mechanical properties such as yield strength, hardness and ductility.
In order to understand why these factors, i.e. the number density and potency of the inoculant particles, affect grain size we need to understand the role of constitutional supercooling (CS).
It has already been mentioned that temperature gradient is an important process factor but other factors such as interface growth velocity and cooling rate also affect the microstructural outcomes as shown in Fig.11.
Both of the above factors would increase the likelihood of nucleation as the layer grows.
It is also likely that other factors such as scan speed of the AM device will affect the parameters shown in Fig. 11.

These results indicate that the chemical composition of brass has a significant effect on acoustic properties.
Therefore, clarifying differences in the acoustic properties of materials is important for product design and improvement.
Microstructure is closely related to material properties, and twin in particular is known to affect vibration properties.
This difference cannot be explained by a mere dimensional error, and is likely due to other factors such as microstructure in addition to changes in physical properties.
On the other hand, C2800 was not affected by twin, but the difference in microstructure caused by exceeding the solid solution limit of zinc may have affected the acoustic properties.

Results and Discussion Mechanical performance of PLA/Tencel blended Yarn.
Tensile properties of PLA/Tencel blended Yarn are shown in Table 2.
The quality of the product, yield, cost, and the handling property were affected by the twist.
Different kinds of fibers have different twist factors.
In order to understand the tensile properties and twist factor of PLA pure yarn and blended yarn, the tensile properties of PLA pure yarn and PLA/Tencel (50/50) blended yarn with different twist factor are analyzed.

The effect of vibration on the human body is related to the natural frequency of parts of the human body affected. 
The results of these reports indicated the resonance of the human body depended on various factors: the posture, the materials of the given seat surface, vibration magnitude and frequency.
Although the human body is a unified and complex active dynamic system, lumped parameter models are often used to capture and evaluate human dynamic properties.
The masses are connected together in the vertical direction by mass less springs and dampers that capture human viscoelastic properties.
Most affected parts ale the organism are head (the neurological systems) and the thorax (the breathing).

Previous studies only show the individual impact of these concrete recycled materials on mechanical and durability properties.

For HA coating, two factors are of primary importance (3) .
The first is whether the changes in the composition and properties of the coating materials damage their in vivo performances.
The nanostructure has better mechanical properties and stability in vivo, perhaps this is one of factors by which the WS samples have the highest push-out strength between implants and bone.
However, completely crystalline HA coating is not beneficial since the completely crystalline HA coating would have worse mechanical properties and inhibit both cell proliferation and alkaline phosphates activity (6,7) .The Ca.
In addition, the amorphous phase and nanocrystals were also beneficial in inhibiting crack formation and better fatigue properties than a crystalline coating, Therefore, it is important to retain some amorphous phase and nanocrystals in the coating to enhance the mechanical properties

Wide spectrum of factors affects durability of cutting tools, which is important to study and analyze to point out the differences in this process.
In addition to used cutting material there are more parameters affecting cutting process.
Material for workpieces is from specific material list with guaranteed chemical structure and mechanical properties.
Material for cutting tools defines theirs machining properties.
Testing properties of those materials are very important, because their properties may be different than properties defined in standards ISO.
