Test Results According to the experimental data, the relationship between the fatigue life (N) and the crack length (a) are shown in Fig.2.

It is known that for a point force applied at ξ with respect to the main crack-tip, the following potential functions are given by [5]; (2) where γ stands for the dislocation data and is given by [6]; (3) For a force dipole as shown in Fig.1, previous potential functions Eqs. (2) can be written as; (4) and using the following differential operator; (6) (5)  Eqs. (4) become;
As evident, a micro crack located closer to the main crack dominate the resulting interaction effect and reflect an anti-shielding of the damage while a reduction constitutes a material toughness. 4- Conclusion It is shown in this study by using potential complex based on Muskhelishvili’s formalism; Green’s functions for the Stress Intensity Factor are employed to quantify the effects on a crack of a micro crack represented by a dislocation dipole.

One of the limitations of investigations [1-3], is the large number of experiments to provide sufficient data for the theoretical model.
By combination of hyperbolic tangent and Preisach models, a new hybrid model was proposed to simulate the frequency-independent and frequency-dependent hysteresis, which leads to reduction in the number of tests required.

According to build good experimental platform, measured data is shown in Fig 6.

The factory offers the data: The performance parameter of steel material of the bottom of projectile (Medium A): ，，，，； The performance parameter of support-tile (Medium B) :，，，，； The performance parameter of connection-part (Medium C) : ，，，，。
Reflection wave and transmission wave are both load reduction wave.

Until the end of the fiber under the role of the interior light reduction device get the convergence beam scattered out to lighting.The entire optical path map as shown in Figure 1.
Therefore, the above data into the empirical formula(1-1), Can be calculated Ae =0.111483m2 .

., Ltd.) and Data Precision Photometric Test Instrument (Heshan Perfect Dyeing Equipment Factory Co., Ltd.) were used during dyeing and testing.

Ultra precision machining generates extreme geometrical accuracy and surface roughness in the case of larger dimensions, while micro machining aims the main principle of size reduction.
An etalon unit was measured be the microscope, too, so the surface roughness data can be weighted, and compared to the results of other measuring methods.

The simulation starts from the first month, with the advent of the random number , also the consumption of the month is , corresponding reduction inventory is .
Table 2 Satisfaction in different quota number Quota number 1 every year 2 every year 3 every year 4 every year Satisfaction rate 54.00% 86.72% 97.48% 99.56% In the condition of MTBF is 4 months, assume that a unit have 4 years consumption data, assume that the average annual consumption is 2 when the upper limit of low consumption repairable parts. 4-year cumulative consumption is 8.

In the case of carbonation, chemical reaction between carbon dioxide from the air and the hydration products of cement in concrete causes a reduction in the alkalinity of concrete and consequently in its ability to protect the steel reinforcement from corrosion [3-6].
Fig.3 CT photo of the specimen Conclusions Observations and data presented in this paper support the following conclusions: Longer carbonate time leads to greater depth of carbonation, and fly ash may accelerate the carbonation of concrete materials.
