In the past, researches were mainly concentrated on the mechanical properties of concrete under high strain rates when concrete structures beard impact loads, such as shells, bombs and explosions, but the study of structures in the course of normal use had not been paid enough attention to [3].
Thus the awareness of the mechanical properties of concrete under dynamic loading, such as the effect of the increase of loading rate on the improvement of strength, is still in controversy.
This is of great significance to realizing the dynamic mechanical properties of concrete and the improvement of the dynamic design of concrete structures as well as the ensuring of structural safety.

The maximum settlement of the structure is regarded as the index of underneath the subway construction and design in this article, the mechanical parameters for pipe shed reinforcement layer on a subway station passing through the existing structure is back analyzed by utilizing the orthogonal experiment design methods, and the mechanical integration properties parameters which is close to engineering practice including elastic modulus, Poisson ratio, cohesion and internal friction angle for the material in the pipe shed reinforcement area are got.

By visual analysis [6, 7] different level of test index mean value of factors and different factors range list in table 2.
Importance sequences of factors are listed in table 2 according to a rule that the bigger the range, the more important factor is.
Finally the combination of best level of factors is the optimal factor scheme.

The spontaneous phase transformation of the unstable phase II to the stable phase I of isotactic polybutene – 1 can be affected by several factors (temperature, pressure, mechanical deformation, environments, nucleation agents or presence of –CH2- groups in polymer chains or in blends).
The resulting polymer has a high molecular weight, which contributes to excellent physical, mechanical and chemical properties (such as creep and cracks resistance, good mechanical properties and excellent elastic recovery, resistance to many chemicals; physical, environmental stress cracking effects and high temperatures).

In order to refine the microstructure and improve the mechanical properties of the thicker steel plate, the large rolling reduction should be conducted.
Introduction Requirement of thicker steel plate with fine microstructure and excellent mechanical property are improved with rapid development of state economics [1].
The inner mechanical property of steel plate is not as well as in the top and bottom surface, the reason is that the inner region can not get enough deformation [2].
The deformation in the center was improved and then the strip mechanical property was improved.
Roller speed ratio (the divided value of bottom and top roller speed) that will not only affect effective strain along plate thickness but also affect plate shape after rolled is an important factor during constitution of snake rolling process.

Residual stress of work piece surface is affected by both thermal and mechanical effects.
In the 1st report1), we have proposed a new technique for eddy current sensor to avoid misdetection caused by the dispersion of material properties of work pieces, and its effectiveness was confirmed.
It is well known that tensile residual stress is one of the most critical factors to reduce the fatigue strength of the work piece.

From these results, we can state that machining heat was not enough to change the metallographic structure of each work piece, and the residual stress was strongly affected by the mechanical effect in this examination.

But the poor bond performance between inorganic filler and organic polymer material matrix has become a bottleneck[2] to restrict the improvement of bone scaffold mechanical properties.
The artificial bone scaffold pore size and mechanical properties can be adjusted by changing the binding layer thickness.
The mechanical properties of the materials are listed in Table 1.
Therefore, the Young's modulus of HA artificial bone scaffold reach the maximum and the mechanical properties is optimized when the adhesive layer thickness is .
This also shows that HA artificial bone scaffold's mechanical properties can be changed by adjusting the thickness of adhesive layer.

Joint configuration is mostly affected by the material parameters and process type.
The various properties of the sheet metal are assumed to be function of temperature.

Introduction The silicon carbide (SiC) reinforced aluminum matrix composite has been considered as a promising material in high technology fields owing to its high specific strength and stiffness, excellent high temperature properties and wear resistance.
In metal matrix composites (MMCs), the cohesiveness between the matrix and the reinforcing particles is also an important factor affecting the mechanical properties of the MMCs.
In the present work, a simple microwave-enhanced wet etching method was applied to modify the SiC surface and its effect on the chemical and mechanical properties of Al/Cu-coated SiC was examined.
The compaction, sintering and mechanical properties evaluation using three-point bending test (ASTM B312-96 specification) were conducted following the same procedure described in ref. [5].
The amount of dissolved copper into solution was dependent on the surface properties of the SiC materials.
