The results show that crack orientations and the load conditions of tunnel affect stress intensity factors significantly.
It is a nondestructive, whole-field, graphic stress-analysis technique based on an optical mechanical property called birefringence, possessed by many transparent polymers.
The method relies on the birefringence property exhibited by transparent plastics [13, 14].
The fringes of the principal stress difference and the corresponding stress intensity factors (SIF) near the crack tip A under uniaxial compression are shown in Fig.3.
The fringes of the principal stress difference and the corresponding stress intensity factors (SIF) at crack tip A are shown in Fig. 4.

Such factors as material parameters, winding angle and dimension affecting the mechanical properties of the rigidized tube are taken into account individually by fixing the other factors.
As shown in Fig.5, three curves of the mechanical properties have the same trend.
Furthermore, there is a notable change in the mechanical properties for L/D less than 20, also in Fig.5.
When L/D is larger than 20, the mechanical properties decrease slightly.
It is found that the winding angle and the ratio of length to diameter affect the mechanical properties significantly.

Experiment Research on Tensile-shear Behavior of Spot-welded Lap Joints of Ultra-high Strength Steel with Common Steel Xiang Lia*, Xiaoyang Lib, Huiping Yuc, Ya Li Mechanical and Electrical Dept of Beijing University of Technology, Beijing, China, 100124 a*lingda_lixiang@126.com, blixy@bjut.edu.cn, cyuhuiping@bjut.edu.cn Keywords: Ultra-high strength steel (UHSS), Common steel, Spot-welded, Mechanical properties Abstract.
Therefore, it is particularly important to do some relative research on ultra-high-strength steel and dissimilar materials’ welding properties.
Jie et al.[4,5] divided the metal around nugget into weld nugget zone and base metal by using local stress analysis methods and studied the nonlinear mechanical properties of spot-welding lap joint’s structure in the tensile and shear state.
Such deformation generated maybe because of the complex surrounding tissue components of the weld nugget and uneven material properties.
Secondly, the electric measurement detection values are determined by many factors such as varistors’ quality and the interference between the wires.

The reactions in hydration process cause some complex particle to be produced that affect the mechanical properties of LFC.
The addition of polypropylene fibre retains water, and more air will be entrapped thus affecting the properties of LFC.
The reaction happened will change the microstructure formation thus affecting the thermal properties.
Some complex particle is produced in hydration process which affects the mechanical properties of LFC.

This work investigated a variation in mechanical properties of alumina as a presence of two types of dispersed phases: strontium hexaluminate and calcium hexaluminate.
These mechanisms can incorporate and promote superior mechanical properties.
Lower sintering temperatures could be possible when some sintering aids are used, which the chemical stability as well as mechanical properties could be affected form glassy phase at grain boundaries [3].
Vickers indentation and bending test was employed in order to evaluate mechanical properties of the composites.
The mechanical properties of the three-component alumina-based composites were presented in Fig.2, showing an existence of the hexaluminate phases mostly gave rise to all properties compared to the monolithic alumina.

SiOx/PET thin film as food packaging material, exhibited not only a high barrier property, a good mechanical property, a safety, a transparency, but also had an excellent microwave permeability.
In order to further optimize magnetron sputtering parameters, improve ceramic films’ barrier properties, and accelerate the process of the films’ application, the coating SiOx film on PET substrate parameters were studied in this article.
Magnetron sputtering technology involved many factors, and each factor has the different levels, and they are intertwined, very complicated.
