Several properties of thermoplastic nylon are biological, physical, chemical and mechanical properties.
One thing to be considered in the act of denture was the denture based material mechanical properties.
Those properties are important because it would affect the denture usage duration [11].
Pressure transmission difference occurred due to several factors such as denture base materials and denture tooth selection [14].
The crystallization stages could affect the materials properties such as modulus of elasticity, hardness, stiffness, and etc [2,15].

It was shown that the surface engineering and modification of surface chemical properties by various surface passivation treatments, deposition of hydrophobic coatings and lubrication with low surface energy self-assembled monolayers are effective methods for enhancing the fabrication and tribological performance of MEMS, but it was not concern with the effect of electrostatic tangential force in the MEMS devices.
Because of the surface falling charge, any surface can produce charge and then produce the electrostatic field and form a resistance to prevent the move between two parallel and charged flat mechanical elements.
These bumps would affect electrostatic field between two parallel plates, and lead to the capacitance and electrostatic resistance to change.
The factors of the applied voltage, the rate of all micro bumps projective area to the moving plate area, and the relative surface roughness are primarily considered to examine the electrostatic resistance between two charged moving elements.

., creep temperature), cause diffusive processes affecting the structural stability, and mechanical properties of the welds.
The use of Regulations VGB as a comparison standard showed that the hardness properties of variant No. 1 were superior than variant No. 2 which exceeded the allowed VGB hardness values.
In addition, the presence of diffusion-affected zones, especially carburized zones, were observed.
Differences in mechanical properties in different regions of the heterogeneous welded joints result from these thermodynamic processes.
An important factor that can affect the stability of heterogeneous welded joints is the use of suitable consumables, which can significantly reduce the effects of any alloying element concentration gradient in the base material as demonstrated in variant No. 1.

In the following, the improved ESAD device which uses optimized opto-mechanical components is presented.
Schematical view of the opto-mechanical set-up of the ESAD device.
ESAD shearing deflectometry thus incorporates three central metrological advantages: (1) ESAD is based on the propagation of light as the primary straightness standard. (2) ESAD ensures optimal measurand (angle and length) traceability to the SI units. (3) ESAD benefits from the error-eliminating properties of the shearing (difference) method.
Figure 2 shows the opto-mechanical set-up of PTB's ESAD device [3-6].
A comprehensive analysis of different error influences affecting ESAD measurements and detailed uncertainty budgets were published [3,4,6].

Shrinkage and creep are the inherent properties of concrete bridge.
Introduction Shrinkage and creep are the inherent properties of concrete bridge.
Because a lot of factors affected shrinkage and creep are various related to time and environment factors, the internal force and long-term deformation of concrete bridge are obviously uncertain.
The mechanical performance analysis of these predicting models are all based on determination factors, which induces much deviation between calculation and real structure.
According to the uncertainty analysis for influence factors of ACI 2009 and CEB-FIP 90 model, In Hwan Yang determine the value of uncertainty parameters in shrinkage and creep model, material properties and environment variety [1].

The main causes of the failure of con-rods are fatigue and other factors according to the previous investigations [9-16].
Materials and Methods 2.1Materials Although there are a number of materials available in the market that can be used for manufacturing con-rods, the material used should be carefully selected and it should have good mechanical properties [32]. 42CrMoA has a good combination of strength and toughness in the quenched and tempered conditions [24].
The safety factors of other parts of con-rod are shown in Table 5.

For TiN/3Y-TZP, the matrix particle size is the key factor responsible for its low temperature degradation resistance.
The LTD severely affected the engineering application of Y-TZP, so it is urgent to improve the resistance of Y-TZP to LTD.
Recent research shows that the addition of TiN particles can effectively enhance the mechanical properties of 3Y-TZP (3mol% Y2O3 stabilized tetragonal zirconia polycrystals) at room temperature [7, 8], mainly due to the close thermal expansion coefficient and better compatibility between 3Y-TZP (10.4×10-6/°C) and TiN (9.3×10 -6/°C).
Lots of research indicates that the dispersing particle size has an important effect on the mechanical properties at room temperature, so it is necessary to research the effect of TiN particle size on the LTD of TiN/3Y-TZP. 3Y-TZP doped by 20wt% TiN, is taken as an example in the experiment.
(3) For TiN/3Y-TZP, the matrix grain size is the key factor responsible for the low temperature degradation resistance while the dispersing particle size has little effect on that in micron range.

Recently, ultra-fine-grained steels with grain size smaller than a few µm have been developed and the mechanical properties were investigated.
These results suggest that fatigue properties of notched member with a fine grain are different from the ones in conventional grain sized steel.
Table 2 shows their mechanical properties.

Abstract The knowledge and control of the structural and morphological properties of nanocrystalline silicon is a fundamental requisite for its proper application in photovoltaics.
The results showed that the nature of the film substrate induces deep changes in the structural properties of the deposited films.
Notwithstanding the large amount of work which has been done to study the structure and properties of nc-Si in the past few years, current scientific knowledge can not provide, however, precise correlations between growth parameters and optoelectronic properties, as the material features are subtly related to the specific deposition technique.
Raman measurements carried out with the 488 nm laser showed that for both sets the crystallinity of samples prepared with dilution factors lower than 20% is higher than 60% and almost uniform across the wafer.
The results have clearly demonstrated that the structural properties of the nc-Si films are strictly related to the substrate nature, particularly for high silane dilutions.
