Introduction Image testing methods to analyze the material properties and defect distribution is the most commonly used method in Ultrasonic testing.
At present, judgment work mostly accomplished by manual according to certain criteria in most of the actual testing, judgment results would affected by subjective factors.
Ultrasonic C-Scan imaging results are generally expressed as a plane distribution form of the sample information, the signal amplitude variation reflect the factors of the defects within the sample.
The actual effect of defect analyzing is better in the material properties are basically the same conditions.

properties of ZnO films are known to be affected by the residual stresses in the films [1-3].
Mechanical properties of ZnO thin films such as adhesion, stability towards delamination etc.
There are many factors proposed to be playing a role in the creation of these stresses, e.g.
Discussion It is known that the residual stresses in thin films affect the functional (optical, electrical, magnetic) properties of those films.
Hence, it is crucial that the stress buildup is controlled during film growth to achieve strong films with sustainable properties for device applications.

Wiper motor is very high quality requirements and DC permanent magnet motor is adopted, wiper motor installed on the front windshield and worm gears are generally made of one mechanical part.
In optimization on the windscreen wiper mechanism, the objective function is the most important factor, as it not only influence design scheme quality, also can affect the design course.
Instead, a penalty factor was applied to each design if the constraints were violated.
The fitness function is： [ ]{ } 2 6 1 ( ) ( ) max 0, ( )i i x f x R g x ϕ = = + ∑ ，where R-penalty factor，R=28000.

Epoxy resins are one of the most desired packaging materials owing to their elegant adhesion, mechanical and insulation properties.
The structure of the nanofillers strongly affects the particle-to-particle and particle-to-matrix interactions which control the whole properties of the polymer composites [21].

Moreover the thermal damage due to the low thermal conductivity properties of the PLA material also affects the contact zone die-sheet.
The temperature reached by the sheet during the thermoforming process has an influence on the final quality of the manufactured products, affecting both the mould and the thermoformed sheet.
Nonetheless, PLA material shows good frictional properties since the differences stablished in this work in the top surface of the die are less than 1mm after being exposed to consecutive low number of thermoforming cycles (around 25).

The fatigue strength of metals is influenced by many factors, such as surface conditions, defects, microstructure inhomogeneities, specimen sizes, etc.
This microstructural inhomogeneity leads to a resultant variation in mechanical properties such as the tensile strength, the elongation and the hardness.
Finer microstructures generally have superior mechanical properties.
Fatigue properties of cast aluminum components were also affected by interior casting defects [12,13].
The cast defects on the surface of group A, which deteriorates the fatigue behavior, together with finer grain size which benefits the mechanical properties, lead to a lower fatigue strength compared with group B, but a higher value compared with group C and D.

Introduction Specific shear energy consumed in metal cutting for chip removal is one of the important factors to evaluate the machinability of metals.
However, it is difficult to predicated specific shear energy accurately because material properties, cutting conditions, and tool geometry can all affect it.

The manner in which topological defects are distributed is affected by the initial strain and the heating temperature.
Introduction Much of the interest in CNT arises from the mechanical response to severe deformation and strains.
CNTs have already demonstrated fascinating mechanical properties [1-3], and are considered as promising candidates for a new generation of extremely light and superstrong nanoscale fibers.
It is obvious that the temperature is the main factor to determine the tensile yield stress of the tube.
The mechanical and thermal properties of this sort of tubes are under investigation, because these topological defects can influence mechanical and thermal properties of the SWCNT [21].
