Physical and mechanical properties of RSA 443 alloy.
This indicate that all factors are significant.

Hydration heat, one of the most severe factors, makes great effects on the mass concrete construction, especially on bridge structures and dam structures.
So the study of pier concrete heat of hydration properties is necessary for the actual construction.
Calculation Parameters Thermal properties of the concert include thermal diffusivity, thermal conductivity, specific heat and density.
It has thermal conductivity properties.
And the concrete temperature during casting is an important factor affects concrete maximum temperature.

Besides the factors of material composition, the storage medium (artificial saliva), temperature (37oC), and contact area (surface area exposed to artificial saliva), another factor that affects the rate of ion release is the immersion time.
The composition and filler load affect the mechanical properties of the material.
Mechanical properties generally increase along with the increase of filler load.

The review end with the discussion about critical factors and suggestions to incorporate nanocomposites into AM to get functional 3D printed parts.
For example, the viscosity of a UV-curing resin can affect the mobility and dispersion of NP which can lead towards lack of dispersion and affect overall desired properties.
The lower cross linking density leads to poorer mechanical properties.
MWNTs enhanced the mechanical properties (except tensile elongation at rupture), thermal stability, and electrical conductivity properties of the PA11.
Furthermore, the sensors can be easily printed in different geometries, expanding their utility to wearable form factors.

Due to its chemical composition and mechanical properties is can replace non-aesthetic caps or metal crowns.
Introduction Zirconium dioxide is a material which is unique in terms of its mechanical strength.
There have been performed numerous studies on determining the static mechanical properties of the material after synterisation; the process of hardening, however the available literature presents to very little extent the studies of determining the S-N curve.
A lack of the tendency of a definite relationship between those parameters shows that potentially other factors were essential, e.g. due to a considerable shrinkage of the material, the course of heating and cooling or the homogeneity of the material[4].
It can therefore be concluded that the conditions in which material is placed (water, dry environment) does not have critical affect on the mechanical properties.

Introduction The main goal of mechanical surface treatments of metallic materials is the enhancement of fatigue properties.
Therefore it is the aim of this paper to examine which factors control the stability of macroscopic residual stresses in high temperature fatigued metallic materials.
Some of the most important factors such as temperature and stress amplitude are adressed in the following chapter.
For further details regarding the heat treatment and mechanical properties, refer to [9].
The effectiveness of any mechanical surface treatment of course depends on the combination of applied temperature and stress amplitude, since both directly affect the stability of resiadual stresses and work hardening.

A preliminary seismic analysis of 335 existing bridges was carried out, where in most cases the main mechanical characteristics of bridge elements were unknown and hence some assumptions about significant properties of materials were done on the basis of the original design documents and the construction practice at the time of the structures’ edification.
In-situ and laboratory tests The in-situ investigation campaign has been finalized to define the main geometrical, physical and mechanical properties of the basic materials constituting the 71 examined bridges in order to use these data for the construction of updated Finite Element model much more closer to the real characteristics than those preliminary analysed.
Safety factors FCi have been calculated also for the spandrel wall.
It can be finally observed how safety factors for the arch and the spandrel wall at Safety Limit State are bigger than those obtained at Ultimate Limit State.
For each bridge the significant safety factors FCi have been calculated.

Welding Process Optimization for orthotropic compound bridge plates Yongzhi LIa, Fuyi YUb School of Mechanical and Materials Engineering, Jiujiang University, Jiujiang 332005,China a liyonhi168@163.com，b379913698@qq.com Key words : Stainless steel bridge plates; Orthotropic and compound;Welding optimization Abstract: Compound plates of stainless steel is used to weld under construction in the Southern link’s railway bridge for the first time in China, but there occurs weld warpage of the convex parts and roughness appears excessive on the overall composite plate and severe deformation in the early phase of construction and the quality of railway bridge is affected seriously.
The form of V-type and CO2 welding gas arc welding process are used.There have a larger gap ,large welding field strength and too slow to affect the duration because of the site group.
Meanwhile, the early welding test results show that there occur weld warpage of the convex parts and roughness appear excessive on the overall compound plates, some areas of severe deformation, all of which affect the quality of the weld after forming significantly.So in this paper, the welding forming quality is used to scientific analysis and construction program optimization, it is important practical significance.
Welding image of compound bridge plates Process optimization of welding Preliminary studies have shown that there have many factors affecting welding quality of composite bridge plates and this is a very necessary to welding quality assurance.
Improve the quality of manufacturing cells ⑴The cutting material need specification, and heat treatment must be completed,;there need subsequent heat treatment if necessary and control the accuracy of production unit. ⑵ There has a right cutting-groove technology and subsequent heat treatment in order to eliminate stress and improve material properties. ⑶ Transportation, installation, assembly and other process specifications shall be developed , and it will eliminate roughness, control gap and reduce the stress concentration. ⑷ The design innovation riveting bolts。

On the contrary, the dimensionless parameter is sufficiently sensitive to a fault slewing bearing, it is not influenced by some factors, such as type of slewing bearing, rotational speed and loading.
Non-stationary signal usually contain more abundant information than the stationary one, so the information of the non-stationary signal may reflect more properties of the system[3].
The local properties of non-stationary signal need to be represented by using both the method of time domain and frequency domain, which is called as time-frequency domain analysis for vibration signal.
This method also has the property of reducing noise.
Friction torque are affected by many factors, such as the structure, designation, processing, friction, lubrication, the Fig. 5 Picture of friction torque testing Fig. 6 Temperature curve in accelerated life testing working conditions, etc.

Properties of butt-joint connections of rubber-cable conveyor belts that were in operation are investigated in [11].
Mechanical properties of the belt, including its strength, depend on the amount, relative placement, mechanical properties of reinforcing elements and shell material, and the character of distribution of forces between tractive elements.
Maximum load concentration factors in the middle part are smaller than the corresponding concentration factors in the cross-section x = 0.
Boundary conditions significantly affect the stress-strain state of the belt.
