Introduction Corrosion morphology image is one of the most important features to evaluate corrosiveness of aluminum alloy, it adversely affects the security and integrity of the aircraft structure [1, 2].
Shot peening is often used to enhance the mechanical strength, wear resistance, anti-fatigue and stress corrosion resistance as a mature surface treatment process [4-6].
Currently, no studies are found about the corrosive characteristics and mechanical properties for the shot peening aluminum alloy corrosion.
Its mechanical properties are as follows: tensile strength is 510MPa, yield strength is 441MPa, elongation rate is 8% and Young’s modulus of elasticity is 71.7GPa.
The corrosion mechanism might be related to the following factors: residual stress is formed at the surface of the shot peening aluminum alloy, thus when apply to corrosion, the probability of the stress corrosion for the shot peening specimens will decrease greatly.

They measured the thermal properties and analyzed the key factors affecting the properties of this latent functionally thermal fluid.Eunsoo C et al. [2] studied the forced convection heat transfer characteristics of turbulent flow in a pipe and proposed a three region melting model to analyze the mechanism by which phase change material particles can strengthen the heat transfer coefficient of turbulent flow.Royon and Guiffant [3] described a model to study heat transfer in a circular tube forslurry with millimeter PCM particles.
Numerical results and discussion There are mainly 2aspects that would affect the heat transfer and heat storage performance using MPCMS as the heat storage media, which are the concentration of MPCMSand the vertical space between the tubes.
In Fig. 4c, the area which the convection can affect and the temperature changes is larger than that in Fig. 4b.
The vertical space is another important factor that influence the natural convective heat transfer, and the effect of non-dimensional vertical space of y* (y*=y/R) of 1.5, 3 and 5 were numerically studied by using 10wt% MPCMS as the heat storage media.

In a Gambit was created automatic mesh (Fig. 5.) and was sets boundary conditions (water temperature at the inlet, velocity media, media type and its physical properties).
The SST formulation also switches to a k-ε behaviour in the free-stream and thereby avoids the common k-ω problem that the model is too sensitive to the inlet free-stream turbulence properties.
One of the other factors may be dimensions of the heating element (tube diameter and length), to increase the diameter and length of the spiral tube reduces heating time but also reduce the volume of heated water in the indirectly heated water heater.
Conclusion The results obtained from mathematical simulations of indirectly heated hot water heater, the temperature gradient 80 / 60 °C, it was found that the geometric parameters affecting the thermal performance indirectly heated hot water heater.
The simulations showed that the increase of thermal power water heater affects mainly spiral tube length and diameter spiral tube to a diameter of 0.0445 m beyond the average output of the water heater begins to decline.

Microbending modulator normally consists of a pair of mechanical toothed plates with same cycle, while the sensing optical fibers are fixed in the middle of the toothed plates.
The height, number and pitch of the teeth of the deformer are the key factors which greatly affect sensitivity of the microbending optical fiber sensor.
Conclusion Experimental results show that the sensor has a good linear property.
Due to the limitation of bending level of a fiber, disturbance may occur when the fiber bending level comes close to the maximum degree, which is the reason that the measurement curves reveal the non-linear property afterwards.

The material model serves as a framework for understanding material behavior and establishes the required material properties.
In addition, material properties can be tailored to vary with temperature, thus adding further complexity to the analysis.
In a static analysis, the input data typically includes applied loads 1000 N (fig.1.a), boundary conditions (e.g., constraints and restraints) (fig.1.b), material properties (fig.1.c), and the geometry of the structure (mesh) (fig.1.d).
Modify system's characteristics (i.e., geometry, damping mechanisms, material properties, etc.) to reduce vibration effects.
The natural frequencies and corresponding mode shapes depend on the geometry, material properties, and support conditions.

The relationships among the fiber properties such as fiber density, fiber diameter, fibrous material layer were considered as a factor that influences the sound absorption property.

The interdependence between the magnetic anisotropy of FSMAs, their lattice parameters, microstructure, and magnetostrain properties is considered.
The main physical factors contributing to these dependencies have been analyzed in the framework of magnetoelastic model [30].
We consider these factors to be crucial in the course of determination of MAED value as follows from the next Section. 3.
This equation enables a separation of contributions of these factors.
The temperature dependence of MAED of the Ni–Mn–Ga alloy with MT temperature of about 300 K is almost equally contributed by two factors mentioned above [30].
