There is a great difference in mechanical properties, because Intermetallic Compound (IMC) in traditional weld is easily to damage or rapidly to destroy under the acting force.
In particular, rotational speed is the main factor affecting the welding temperature in Fig. 10.
Parametric optimization is related to the properties of welding process.
In particular, rotational speed is the main factor affecting the welding temperature.
SEM images determine some properties of welding materials.

As a new type of materials, carbon nanotubes (CNTs) have been intensively studied due to their outstanding properties.
Introduction Carbon nanotubes (CNTs) have drawn the interest of many researchers because of their excellent electrical, mechanical, and thermal properties [1,2].
These parameters include the electrode geometry, the magnitude and frequency of the applied AC voltage, the electrical properties of the CNTs and the dielectric liquid, and the duration of the AC field.
The frequency of the AC voltage and the permittivity and conductivity of the CNTs and the dielectric liquid affect the DEP force through the Clausius-Mossotti factors.
is the segment depolarization factor of a cylinder.

Introduction Corrosion fatigue is that structural component is not only affected by cyclic stress, but also eroded by corrosion environment.
During the experiment, the existence of the corrosion medium results in the changes of the generating and spreading properties of cracks.
The mechanical model of analyzing the stress intensity factor can be build, as shown in Fig. 4, in which the internal loads ΔK can be deemed as equal to K.

Model correlations with measurements of ultrasonic and mechanical properties have been performed on several types of inorganic powder compacts in order to provide insight as to the mechanical behavior of interparticle contacts.
The water addition to a castable refractory has a significant and direct influence on the final properties of the castable refractory.
For this reason, influence of water on castable refractory properties has been investigated.
This method gives information about the properties without observing the pores.
These factors reduce compressive strength and ultrasonic velocity.

Fig. 1 General geometry of a typical parabolic spring Literature review Fatigue life prediction is based on knowledge of both the number of cycles the part will experience at any given stress level during that life cycle and another influential environmental and use factors.
In order to make a correlation between phase and mechanical properties, the sample hardness values were also measured for comparison purpose of both near fracture and non-fracture area.
One of the factor that contribute to this is both simulation and analysis used the same geometry and other input like the boundary condition, meshing size and material properties.
The fatigue limits of the same kind of steels can be affected by such microstructural parameters as size and shape of prior austenite grains, martensite, and precipitates and by mechanical properties such as tensile properties [11].

Among the main geological factors to cause the disasters of mine safety production in deep mining, coal and gas outburst is the first major calamity that restricts colliery exploiting.
Among gas accidents, gas explosion, gas asphyxiation, toxic, outburst of coal and gas can cause casualties, destruction of facilities and properties.
Mine direct current electric method is greatly affected by tunnel space and has a small detection range.
Ray-based tomography requires the domain to be discretized in cells having constant physical properties.
The cell size is determined by two factors: the desired resolution and the practical computer limitations.

Collagen, as main component of extracellular matrix, displays several attractive properties.
It has good biocompatibility, does not show antigenicity, is completely biodegradable in vivo and its physicochemical properties can be suitably modulated [13].
Furthermore, with its osteoinductive and plasticity properties, collagen can form a suitable matrix in CaSO4 composites.
There were two major factors affecting the absorbability of the CaSO4/COL composites during the test, one was the collagen content and the other was the pre-treatment.
Mechanical properties and in vitro bioactivity of injectable and self-setting calcium sulfate/nano-HA/collagen bone graft substitute.

Utilizing general finite element software ANSYS, the finite element computing model of the steel spatial tubular joint is built, which is used to analyze the mechanical properties under dead loads through changing its design parameters.
Specifically, the ultimate bearing capacity under dead loads is affected by setting stiffening ring and changing cross-shaped ribbed plate thickness significantly.
Consequently, the impact on the property is significant and it is hard to grasp the mechanical characteristics.
Therefore, in contemporary time, how to improve the mechanical properties of steel spatial tubular joint by changing its design parameters is an attractive topic for domestic and foreign scholars.
However, the value of b increases slightly when t2 increases to 32mm and 42mm, because cross-shaped ribbed plate thickness is no longer the controlling factor at this moment.

The Effect of Fly Ash on Calcium Leaching Properties of Cement Pastes in Ammonium Chloride Solution Hu Yang a, Linhua Jiangb and Yan Zhang c College of Mechanics and Materials, Hohai University, 1 Xikang Rd., Nanjing, China, 210098 ayanghu@hhu.edu.cn, blhjiang@hhu.edu.cn, chhu.zhangyan@163.com Keywords: Fly Ash; Cement Paste; Leaching; Ammonium Chloride Abstract.
The influences of W/C ratio and fly ash content on these properties were analyzed, the relationship between the two factors and the corrosion resistance of pastes was summarized.
Many investigations have reported on the properties of leached cementitious material.
It is known that different addition quantities of mineral admixtures are designed and used in various engineering project, but the effect of different addition quantity on the properties of the modified pastes is not concerned in the literature mentioned above.
The detail of this influencing factor will be discussed in the following section.

Working Parameters Selection of Bladder-type Accumulator Under the Different Conditions Xiaoming Wu1，a, Yanfang Yang2，b 1,2The Department of Mechanical and Electrical control Engineering, Yanshan University PR China axmwu@ysu.edu.cn, byyf3052008@163.com Keywords：accumulator; working parameters; poly index; different conditions Abstract Currently there is a lot of material presented on the selection of different conditions and specific formula in order to select accumulator parameters.
Accumulators have a wide variety of applications in hydraulic systems because of their very useful properties.
Various factors of influencing on working parameters 1) The influence of poly indexr In the charge process of accumulators, the gas index is uncertain.
