Introduction One of the key factors affecting the behaviour and reliability of reinforced concrete structures strengthened with externally bonded fiber reinforced polymer (FRP) composites is the bond behaviour between the external plate and the concrete substrate [1].
This mechanical interlocking is affected by the steel bar profile, bar size, bar surface conditions, concrete cover, and concrete quality.
Mechanical properties of the material are shown in Table.2.
The advantages of FRP vs. steel for this application are primarily the better resistance to corrosion, the ease and speed of application due to the lightweight properties, and the optimization of the grooving process.
And the effective length mainly depends on the physical properties of GFRP or AAB and surrounding material, especially on the shear modulus, namely, GGFRP and GCEMENT.

Therefore, the waist width should be increased to improve the mechanical properties of the whole rail, then augment the mass of the rail.
The corrugated waist rail is one important way to improve the economic properties of classical rail, and it has great significance on the economy and science.
The FEM analysis on corrugated waist rail already test that this special kind of rail structure is superior to classical rail on the lateral flexural, longitudinal stability and dynamic mechanical properties[4].
Fig.6 Rolling force under different reduction 4.2 The Influence of Rolling Speed Rolling speed is a main factor affect deformation velocity, is also main parameter affect rolling force.
Main conclusion is as following: Main factors, such as relative reduction, rolling velocity and initial thickness, can change rolling force, the influence of relative reduction is larger.

The equipment’s processing accuracy, efficiency, reliability and degree of automation affect directly the entire production efficiency and quality of the parts.
That largely affect the optimization level of the process parameters for the band saw equipment, let alone the available numerical control system based on the optimization of process parameters.
This change will directly affect the relationship between the motor’s driving torque and the load torque.
So the dynamic characteristics of the sawing process for the band sawing machine contain many nonlinear coupling factors.

There are many factors which affect springback, such as mechanical properties of the material, friction conditions, and process parameters and so on.
Material Properties Simulation of the forming processes based on finite element method using Dynaform 5.8.1 software requires as input data the mechanical properties of the used materials.
Determination accuracy of the mechanical properties has an important influence on simulation results.
By varying the values of all factors simultaneously, a statistically validated estimate of the results for every possible combination of the factors is possible.
This analysis approach determines not just the primary effects of each factor but also the interactions between the factors.

To this end, we need to find the main factors affecting tissue engineering scaffold degradation in order to grasp the control methods of degradation rate.
These five factors that affect the degradation process is the most critical factor, the ideal degradation modeling should be integrated over five key factors to consider.
Factors such as the first, the impact of molecular structure, there is no one model relates to this; currently most researchers take 1-2 influence of factors into account in the modeling according to the process of degradation phenomena.
Herrera et al [25] established the two-scale model which combined macroscopic mechanical properties of bone with microscopic model of scaffold degradation and scaffold bone growth.
