The thermal fatigue behavior is obviously affected by the environmental factors.

In this work, the effect of heat treatment on the mechanical properties of self-compacting concrete (SCC) was examined.
Mechanical properties tests The mechanical properties of the SCCs were determined by testing cylinders (16x32)cm3 specimens under uniaxial compression and prism samples (10x10x40) cm3 under 3 point flexural according to NF EN 12390-3 and NF EN 12390-5 standard respectively, using an hydraulic testing machine with a capacity of 2000kN (Fig. 3).
In summary, the flow properties of SCC depend heavily on the addition particle size, shape, surface morphology and internal porosity in addition to factors such as mixing regimen, sequence of admixture addition and water/SP content [17, 18].

The mechanical stress was induced on the optical fibers by a micro mechanical stage.
This quality may be affected by pulse broadening which causes the pulses to superimpose leading to poor resolution and detection errors.
Both attenuation and dispersion are responsible of the quality of the transferred signal under the effect of the possible factors that the fiber may expose and result in power loss and signal distortion.
The correlation fringes were obtained by combining the speckle images of the object before and after disturbance, and the correlation properties of the displaced speckles provide information on the value and the direction of the optical fibers strain.
The optical system configuration in the mechanical stress was the same as in figure 3 with the heating system replaced by the mechanical stage.

By determining the necessary work, unnecessary work and shape factors β[2] and other parameters, we can obtain materials’ fracture properties.
From the experiment results, we can confirm that the stress concentration phenomenon affect the EWF method.
So you got three specimens to the experiment: Standard Dumbbell Specimen (SDS), Compact Tension Specimen(CTS) and Double Edge Notched Specimen(DENS), which is shown in figure 1: (a)SDS (b)CTS (c)DENS Fig.1 Geometry of three thick specimen As a viscoelastic material, mechanical properties of the modified double-base propellant is easily affected by production factors and environmental factors.
From the relationship between force (F) – displacement (l) under different tensile rates as the figure 4 shows, we can obtain the following two conclusions: 1) Maximum tension of three kinds specimen increases with the tensile rates, namely viscoelastic properties of the material even containing crack is still obvious; 2) In lower tensile rates, like 1 mm/min, the maximum tension of the Compact Tension Specimen(CTS) and Double Edge Notched Specimen(DENS) is great than Standard Dumbbell Specimen(SDS).
In conclusion, the stress concentration affects calculating stress in the specimen under low tensile rates which causes the tension increases.

One factor that most affect the performance of this device is the wetting properties of the wick material, whereby a hydrophilic wick material is required to transport the liquid from the evaporator to the condenser.
The heat pipe performance has been known to depend on a number of factors, such as liquid properties, liquid charge amount, wick characteristics, and the interfacial bonding in the wick matrix and between the container and the wick [5].
Knowledge of the physical characteristics of the porous material is critical in the design and manufacturing of a heat pipe since its thermophysical properties directly affect the overall performance of this device [6].
This is probably that changing surface properties from hydrophilic to be hydrophobic due to contamination of carbon on the surface of the wick.
These are due to the presence of the carbon element on the wick surface that change the properties of hydrophilic into hydrophobic.

The mechanical properties of ceramic materials are affected by many factors, such as compositions, fabricating conditions (temperature, pressure etc.), equipments, and so on.
These factors, forming complicated mathematical relationship, can be described by data.
His model has achieved good prediction result and ANN is effective in the quantitative prediction of the mechanical properties.
Still there is a distance between simulation and application because the factors influencing the mechanical properties of ceramic material are in large numbers.
Only several factors of them can be simulated at present.
