Typical mechanical properties are Rm = 505 MPa, Rp0.2 = 435 MPa, elongation at break 13% and fatigue strength (limit) 150 MPa.
Therefore, an exact knowledge about FCG rates and various affecting factors is a very important basis for an assessment of residual fatigue life of structures and their in-service safety and reliability.
Since it was a material used for a Proficiency Test Programme (PTP) organized by Exova company for laboratories being involved in accredited testing for General Electric Aviation group, it had particularly homogeneous composition, mechanical and fatigue properties.
The only disadvantage was a very high price, but on the other hand, the characteristics affected reproducibility of experimental measurements very positively.
Though the alloy was homogenous concerning mechanical properties, it contained numerous areas with strong clusters of inclusions – Fig. 2.

The surface roughness is affecting the detecting capacitance of MEMS device because surface to volume ratio is increasing rapidly.
Introduction Surface roughness plays important role in various electrical properties.
It can affect electrical properties such as electrical capacity, electronic conductivity, surface energy, critical area, peak electric field, surface tension, sheet resistance, etc.
Hence, the impacts of surface roughness on electrical properties of detecting capacitance with one smooth electrode and one rough electrode were investigated in this paper.
Image of height histogram and height percentage on the electrode sample The shape of the electrode perturbation is one of main factors affecting the capacitance values.

However the casting products have poor mechanical properties than those of wrought products.
So many studies have been conducted to improve the mechanical properties of cast Al alloy.
VAL12 shows good mechanical properties having an ultimate tensile strength of 513MPa and 2.5% elongation.
In order to extend the applications, it is necessary to investigate the fatigue properties of the alloys.
In previous section, the major factor affecting the low cycle fatigue life was explained by the crack initiation and its easiness was related to the lower tensile strength of the alloy.

It is used in a variety of micro structural conditions, depending on the properties desired.
Previous studies have suggested that the fatigue behavior and mechanical properties of α+β titanium alloys are greatly influenced by their microstructures.
Many of these researches have an overall view on microstructure affect on fatigue crack growth rate with no attention local view of microstructure affect on crack growth path.
The shape of this microstructure is shown in Fig.1; the composition of the material is given in table 1 and table 2 specifies mechanical properties of Ti-6Al-4V forged plates.
Room temperature material properties of Ti-6Al-4V forged plate Fractography.

During the service process of a P.C. bridge, the mechanical properties of materials (including concrete and steel) will deteriorate, and eventually result in the decrease of ultimate bearing capacity.
Because of the reinforcement erosion and corrosion cracking of cover layer, the effective section of steel will decrease and mechanical properties will deteriorate.
Besides, the bond behavior of concrete and steel will deteriorate too, which affects their cooperative work.
In this section, Plive load is lane load, and λ is load factor.
The load factor on limit state when t =100a was 7.8265.

Thus the mechanical properties of a formed part vary spatially over the part.
High springback often results in the formed component being out of tolerance, introducing extra problems during the final assembly and also affecting the aerodynamic behavior of wing panels.
However, it is still a preliminary set of constitutive equations for CAF, and some important factors, such as the volume fraction of precipitates, are not included in the equations.
In order to optimize processing parameters and further popularize the industrial application of the technique, some aspects that need to be focused on in the future are as follows: (1) Experimental study of precipitation formation and growth under stress and strain conditions showed that stress and strain do affect the precipitation evolution, orientation and mechanical properties [18-19].
However, one of the most important features in CAF is the improvement of mechanical properties.

It was used widely in aerospace industries, because of its ideal properties.
It is also a quite complicated process to implement This technology directly affects the properties of products and working efficiency.
In practical application, however, most of path planning methods published only consider pure geometric factors and few methods involve mechanical factors for the sake of simplicity.
A few methods[6,7] did consider mechanical properties such as loading information and so on.
So, for the complicated surface geometry, topology, and varying mechanical properties within one mould surface, the fiber placement with multi reference paths might be worth probing.

It exhibits exceptional structural, electrical, and mechanical properties [15].
Because of the electron spin-orbit coupling factors, Ti2p energy level is divided into the Ti2p3/2 and Ti2p1/2.
But in this experiment, chemical composition is not the main factor which affects the frictional properties of the film.
The adhesion properties can directly affect the use of coated tools.
So, temperature is an important factor affecting the adhesion properties.

Fine microstructure and excellent weld shape can be obtained by choosing reasonable technology parameters and the mechanical properties of welding joint can also be promoted.
The increasing of Al in magnesium alloy is beneficial to thinning the grain and to improve the mechanical properties.
The Mechanical Properties of Welded Joints of Magnesium Alloy Wang et al [17] used CO2 laser welding system to weld AZ31 magnesium alloy and studied the microstructure and property of the welded joints.
This shows that using laser welding technology to weld AZ31 magnesium alloy can improve the mechanical properties of welded joints.
The pores may be reduced by adjusting the parameters, preheat and eliminating the factors of gas, but they can't be entirety avoided[21].

Those are properties such as (strength, heat-insulating properties, water absorption, etc.) of concrete throughout the entire volume of the product.
