Introduction In the continuing requirement for automobile weight reduction, the 6000 series Al-Mg-Si alloys has been considered as the promising candidates for age-hardenable bodysheet materials.
The hexagonal networks of the bright dots of the precipitate are observed in Fig. 3(c) with the spacing about 0.7nm, and the direction of the precipitate (indicated as P) is inclined by 10o to the <100>Al direction of the matrix which is similar to the data shown in for the β' phase [7].

Once the load reaches the ultimate bearing capacity, the reduction of load will lead to the rapid energy release from the device, and at the same time, it will impose a very large extra stress to the specimen, which will cause the sudden failure.
Fig.4 The whole failure process of uniaxial tension specimens The same strength grade and strain rate of the complete stress-strain curves for uniaxial compression concrete were obtained by analyzing the test data.

Simulation equipment, apparatus, during the experiment through the software simulation, greatly reduced the cost and size of instrument hardware and software for data through the display, storage, and analysis and processing.

So this study provides experimental data and design for the application of laser surface micro processing technology in the reduction of test piece’ friction coefficient.

It has been shown that this structure is very sensitive to initial imperfections, and the existence of the imperfection leads to a significant reduction in the stability load-carrying capacity.
It can be seen from Fig.10, the max stability load–carrying capacity is about 4100×103N.However,in the paper, E=2.1×105Mpa，L=3015mm，d=195mm，these data are put into ，the result is 4039.5×103N in the theory.

There is no reduction to live load and infill walls, but the impact on the natural period of the structure is ignored.
For statistical data has full of comparability, this article will equivalent conversion the steel structure house model of the secondary beam and floor as the two-way floor uniformly distributed live load applied to the two directions of the steel main beam.

The use of TBCs can result in a temperature reduction of 100-300 ℃ at the metal surface, thereby improving the durability of the metal component and enhancing engine performance [1-5].
At least twenty data were measured at 30 or 50µm locations to obtain average values of Al concentration.

The mechanical properties are: 449 MPa tensile strength, 283 MPa lower-yield strength, and 69% reduction of area.
The dotted line is data for overloaded specimen and solid line is for baseline.

With the reduction of oxygen concentration, the great weight loss rate gradually increased.
Each sample correlation coefficient of fitting equation is close to 1, so the experimental data is fit to linear regression.

Oh et al. [1] researched on the drilling torque which was estimated using the spindle motor current and controlled through feed rate manipulation for the reduction of drill wear, cutting torque measured indirectly from the spindle motor current.
The data sampling frequency was 1000Hz, The processing site shown as in Figure 5.
