During modeling it is approximated by an ideal homogeneous cantilever having material properties of bulk nickel.
Because the system surroundings are in equilibrium, the only force component that affects the moving microstructure results from the additional film pressure ∆p.
Quality factors listed in Table 1 indicate that in this particular case the level of air damping is relatively low even at atmospheric pressure.
These results demonstrate that under the effect of squeeze-film damping the quality factors of the analyzed microsystem may be reduced to as low as Q ≤ 1.
It was found that predicted quality factors are in good qualitative agreement with approximate analytical values in the pressure range of 1 ÷ 100 kPa.

Ballistic Materials In designing soft body armors, high strength and high modulus fabrics are most essential properties [1,3,6].
Table 1 display the mechanical properties of most common ballistic grade materials [2,4-7].
Table 1: Mechanical properties of typical ballistic fibres.
This affects the frictional interaction between the yarns and thereby improves the ballistic properties.
However, it is important to notice the factors concerning with armor product design and development.

As it is well known that the behaviour of passengers is a very complicated factor to accommodate in the elevator model.
The special case mr=0, i.e. the empty car, is not important when considering ride quality but are of importance for maintenance or noise effects affecting the building system.
The technique presented in this paper seems to be sensitive enough to identify the mechanical response of passengers wearing different type of shoes in order to provide criteria for optimal covering floor properties of elevator cars.

There are different at the sensing properties and detection principle of gas sensitive materials.
Hydrogen sensor detection principle is based on physical or chemical property change of gas sensitive material after the adsorption of hydrogen.
Hydrogen gas sensitive element is the core component of hydrogen sensor, testing results was directly affected by its performance.
Working temperature is one of the most important influence factors for hydrogen sensor.

Specific steps: (1)to find out the components of the foundation soil, that is determining the size and content of the large mass, such as rocks, tree roots and so on, to avoid the large objects becoming obstacles to the construction of cement-soil; (2)to determine the naturally stable moisture content of soil, while the dosage of cement-soil keeps the same, the strength of cement-soil increases with the decreasing of moisture content; (3)to determine the organic content: a high content of organic matter in soil will hinder the hydration reaction of the cement, and affect the strength increasing of cement-soil, so we must find out the amount of the organic matter, determine its influence degree on the strength of cement-soil, and take the corresponding measure; (4) to determine the PH value and sulfate content of soil, if the PH value is low, lime can be used to have a balance, and the sulphate resistant cement or other admixture should be chosen when the sulfate is too much; (5)to
carry out the physical property tests of soil, which can provide design conditions through the data of soil’s specific gravity, dry density, natural bulk density, liquid limit, plastic limit, compressibility, compression modulus and so on.

To overcome the flaw of the mechanical movement an electronically tunable reflectarray antenna based on non-linear properties of Liquid Crystal materials has been introduced.
Non-linear material properties have been used to develop an algorithm based on Method of Moment, for dynamic phase distribution of three resonant elements.
Liquid crystal materials can be realized as a dynamic phase control strategy in reflectarrays due to their non-linear dielectric properties [4, 5].
Table 1 summarizes the properties of non-linear dielectric materials that are used to design the reflectarray resonant elements.
Therefore a MoM algorithm for dynamic phase range based on non-linear material properties has been established as shown in Eq. 4

New perspectives have opened for the manufacturing of products in precision engineering and in medical instrumentation not only by the special mechanical, optical, biochemical etc. properties but also the electrical ones of carbon black dotted silicone rubber.
This modulus is defined as 22 EEE ''+'=∗ further we obtain the material loss factor with EE '''=δtan .
The electric properties of the carbon dotted polymers are determined by the type, amount and the size of particles [6].
However the percentage of carbon strongly influences the mechanical properties of the material.
This pulling force can be affected by the pressure.

The strain distribution within a grain seems to be affected by neighbor grains.
Introduction Measurement of inhomogeneous strain is an important and interest matter for material science and engineering, because inhomogeneous strain connect with material microstructures which dominate mechanical properties, such as strength and fracture.
As referring with the Schmid factor and Taylor factor, apparent deformability in each grain varies with the grain orientation due to different shear stress on a slip system.
Grains deformed easily with a low Taylor factor are probably subjected to additional deformation imposed by their neighbouring grains deformed difficulty with a high Taylor factor.
Strain distribution in the Grain 4 was significantly affected by neighbor grain.
