Factors affecting the tensile properties include (i) the presence of additives, impurities, or fillers, (ii) environmental conditions such as temperature, humidity, and (iii) physical properties including geometric size and shape, orientation, morphology, crystallinity and surface condition.
The mechanical properties of nanocomposites are influenced by factors including dispersion, particle surface area, and the intermolecular interactions of different functional groups present in the matrix and filler of the composites [49].
The variation of mechanical properties of different nanocomposite films is shown in Fig.8.

The finishing effects of tussah silk fabric including wrinkle recovery angle, whiteness and mechanical properties were characterized.
In order to overcome inferior textile properties, considerable interest in the improvement of the such as anti-yellowing, wash and wear properties, and crease proofing of the silk with some kinds of chemicals have been attempted[4-6].
The effects of the technique factors on the results of wrinkle resistant property, retention rate of breaking strength and whiteness were analysized.

Generally, mechanical properties become poorer as loading amount increase.
Melt Flow Index values for physical properties also provide same trend as mechanical properties results.
Furthermore, it is well-known that particle size plays a major role and important parameter of flame retardant additives, which possibly affect the mechanical properties and fluid properties of composites.
As a result the competition between these factors indicates the trend of change of tensile properties.
In addition, these improvements can be attributed to two factors.

Abstract:Coarse-grained soil is widely used in subgrade engineering, creep property of which is the important factor that affects long-term settlement of fill embankment.
It turns out that moisture content is the important factor that affects creep property of sandy slate coarse-grained soil and using dry or saturated coarse-grained soil is able to decrease long-term settlement of embankment.
Creep of coarse-grained soil is resulted from compositive factors including category, moisture content, and depth of filling, etc.
In the past, researches on the factors that influence creep are mainly concentrated on rock[1], soft soil[2-3], loess[4] and expansive soil[5], etc, but few of them are about the study related to coarse-grained soil.
As for Viscosity Coefficient β(refer to Table2), the change regulation is similar to ε but not that obvious, for viscosity coefficient is the complex performance of mechanical property of coarse-grained soil creep.

Drum Sludge Drying Equipment Energy Dissipation Factor Analysis Xiaolu Ma1, a, Yong Zhang2,b 1School of Mechanical-Electronic Engineering, Henan University of Technology, Zhengzhou 450007, China 2School of Mechanical-Electronic Engineering, Henan University of Technology, Zhengzhou 450007, China ayy0096@163.com, bzy15890602541@qq.com@haut.edu.cn Keywords: Drum sludge hot drying.
Influence factor Abstract.
In view of the sludge drying energy consumption problems, we summary and analyze drum sludge drying equipment all aspects of the energy consumption factors, the hope can turn to improve the drum sludge drying equipment energy utilization, reduce the energy consumption.
So a lot of the organism and the sludge particles have certain adsorption and bond properties, which promote wall sticking in the process of sludge drying, and then will reduce heat transfer efficiency of sludge, hinder the evaporation of water from the sludge, which can reduce the drying speed, cause waste energy.
We can see wall sticking of different temperature from figure 2, which affect energy consumption.

Then, relevant factors which may affect the process are studied, and some measures to enhance the threaded fitting reliability are proposed.
Thermo expansion coefficient and the high temperature mechanical properties of the joint material codetermine the format of variation of bolt tension. 3.2 Effect of preload Generally, increasing the preload of the joint is a practical approach to improve bolt tension at high temperature.
Therefore, the ratio of high temperature period of the total cycle time should be one of the main factors affecting the bolt tension variation.
Then the effects of relevant factors are investigated.
While bolt tension will be higher at low temperature for bolted joint that bolt expands more than the clamp parts do. 2) Residual bolt tension at high temperature is mainly determined by the yield state of the bolted joint, which is directly affected by the material mechanical properties at high temperature.

This research was study the effect of resistance spot welding process on physical properties.
Factors affecting the tensile shear are the most welding current of 12,000 amp., welding time of 8 cycle and electrode force of 2.5 kN. were tensile shear of 9.83 kN.
Because if the selection condition on access to inappropriate, would have affected the mechanical property which reduced the strength of work pieces.
Use the experimental design is a full factorial design (2k) to be the main factors effectors affecting significantly.
Factors affecting the nugget size of a maximum were welding current of 12,000 amp., welding time of 12 cycle and electrode force of 1.5 kN.
