The surface undulation was affected mainly by several factors: the surface morphology affinity to cylindrical shape, reduction of the real area of contact and air pockets trapped in cylindrical double asperities of the surface.
Calculate real area of contact with Hertz and JKR models, the measured mechanical properties, such as hardness and elastic modulus of each layer by nanoindentation was used.
This result implied that there could be two important factors that were affected the adhesion.

Nowadays, carbon fiber reinforced plastics (CFRP) composites is widely used in the aerospace industry due to its excellent mechanical properties.
The factors and their levels are given in Table 1 and also presents the results indicating the effect of pulse energy (A), pulse repetition rate (B), pulse duration (C) and cutting speed (D) on kerf width, heat affected zone and taper angle.
The perturbation plots for the coded values of the process factors and their influence on the top kerf width are showed in Figure 3.
The relationship of these factors is given in the Figure 4.
Whereas, for the bottom kerf width the significant factors are cutting speed and pulse energy.

As integration degree of the circuits becoming higher, the requirement for thermal conductivity, mechanical properties and reliability of substrates become higher too.
For those reasons, carbon nanotubes (CNTs), which have excellent thermal conductivity and mechanical properties [2,3], were adopted to reinforce AlN ceramics.
In this paper, CNTs was used for improving the thermal conductivity and mechanical properties of AlN.
The properties and microstructure of CNTs/AlN ceramics were primarily studied in our present works.
Because of the density is one important factor affecting the bend strength and thermal conductivity of CNTs/AlN, so that those two performances degraded with density.

Tensile properties, hardness profile, microstructure of the weld, heat affected zone and base metal were examined.
The present work investigated the microstructure and mechanical properties of laser welded semi-solid processed A356 aluminium alloy.
Mechanical Properties.
The mean values for mechanical properties of A356 at different heat treated conditions are presented in table 3.
There are three main factors which influenced mechanical properties of weld metal and heat affected zone.

Practical experience shows that the mechanical vibration of the offset press is an important reason to affect the print quality.
Analysis of printing part The progress of printing is interaction with many factors.
Of them the important ones are: technology of materials properties, interaction conditions and the ever changing environment.
Vibration of offset printing machine is a critical factor influencing printing quality.
Summary Practical experience has shown that the vibration produced by the printing presses at high speed will make the quality of printed products greatly affected.

Introduction In the past two decades in developed countries, Polycrystalline diamond, traditional cutting tool replacement products, has been widely used in manufacturing, especially processed nonferrous metals and alloys, because of its high hardness, good impact toughness, abrasion resistance uniformity, excellent heat resistance, thermal conductivity and other properties [1].
One is the mechanical grinding.
The affected layer thickness of rough EDM is about 25 ~ 32 μm, the affected layer thickness of semi-precision is about 15~ 20 μm, and the affected layer thickness of precision EDM is about 5 ~8 μm.
So the time of the thermal process is dominant influence factor.
The influence of the electrode material relative weakening, but it is also one of the factors in effect workpiece surface quality.

Abstract: Different Power types and parameters in the electrodeposition process result in different microstructures and hence mechanical properties.
The tensile properties of Ed Cu after Surface Mechanical Attrition Treatment (SMAT) are also shown in this paper.
It is clear that the processing history has a significant effect on the mechanical properties of nanostructured materials.
Since the properties of the materials obtained from electrodeposition and SMAT are strongly affected by the parameters of both processes, room for improvement could be expected.
Mechanical Properties There is various literature which has reported on the experimental results on the tensile strength of Cu.

Therefore, the great energy inside the unprotected prestressed steel cables and steel’s inability to resist high temperature may, once caught in fire, probably lead to the collapse of the whole structure as a result of several factors such as inner force redistribution and the deterioration of structural steel property.
(2) Prestressed loss of steel cables considering high temperature (fire) Prestressed structure and prestressed loss of structure elements are key to affecting its bearing capacity[9].
The mechanical property of structural steel in high temperature can be calculated by using experiment fitting fomula of Tongji University[1].
Therefore, prestressed loss in high temperature is also one of the key factors that affect the stability bearing capacity of structural elements.
Based on analysis above, the effect that the above factors have on structural elements stability bearing capacity should be considered in practical project and some corresponding measures should be taken such as controlling the tension control force, choosing low relaxation cables and setting up fire isolation layer and protection coatings to ensure normal use of the structure.

Lead containing solders (Sn–Pb eutectic alloys) are widely used in electronic devices due to their good mechanical properties and low manufacturing cost.
Similar strength values have been reported by Chen et al. [17] who evaluated the tensile mechanical properties of Ni-Sn-0.7wt%Cu-Ni joints.
Thermophysical properties of alloys used in the experimental analysis [11,20].
The thermophysical properties, the solidification range and the melt fluidity are known as important factors affecting hi.
This fact limited the analysis of the mechanical properties of the Sn-0.7wt%Cu-0.1wt%Ni alloy only for to the growth of eutectic cells.

Addition of fibers in cementitious materials may enhance its mechanical properties, particularly tensile strength, and ductility.
This project is aimed to evaluate the mechanical properties of fiber cementitious materials which comprise fibers and silica fume in the mixes.

TNevertheless, Pearson coefficient only measured the effect of single variable on mechanical properties.
The interaction between each variable on mechanical properties required some further explanations by analysis of variable.
