Grouping experimental method is used to make welded joints soaked, compare the variation law of mechanical properties of flush welded joint under the influence of corrosive environment.
As different areas of base material, reinforced joints have different particularity in connection, mechanical properties and usage of the environment [3].
This paper will study the degradation of mechanical properties of welded joints corroded in the corrosive media under high-stress state.

FeCl2 further diffuses in concrete encountering OH- ,2Fe+O2+2H2O→2Fe2++4OH-→2 Fe (OH)2，immediately produces Fe (OH)2， Fe (OH)2 generates Fe(OH)3 by dissolution and oxidation，Fe(OH)3 further generates nFe2O3·mH2O，Fe(OH)3 does not completely oxidize to produce Fe3O4，and rust layer forms on the rebar surface. 3.2.2 Kinetic conditions of anodic dissolution corrosion Thermodynamic factors and kinetic factors will affect environment.

It is affected not only by the style and design but also by the fabric properties.
ppearan and the intrinsic quality are the most important factors which manifest its value.

The orthogonal experiment methods were utilized to prepare MPC, to study the effect of the factors and the corresponding content on the compressive strength of paste.
And the optimum mix of MPC is ultimately determined, and the mechanical properties and adhesive properties were analyzed.
The strength at 7d is above 90% of the strength at 28d, showing the characteristics of early strength and fast hardening. 2.4 The adhesive properties of MPC mortar The adhesive properties can be measured by the flexural strength of the repaired matrix.

Combining the contact elements into the two-scale homogenization method, the effective mechanical properties of nano-composites with a debonding interface are analyzed.
The basic material properties are shown in Table 1.
The effect of debonding length on effective mechanical properties Debonding interface shows the imperfect of the bond between nano-fiber and matrix, and it is the important factor to cause the nonlinear change of the effective mechanical properties for nano- composites.
The effect of interfacial elastic modulus on effective mechanical properties Interfacial elastic modulus also has great influences on the effective mechanical properties as shown in Fig.8.
The results show that it is limited to improve the effective mechanical properties by only increasing the interfacial elastic modulus. 2.4.

We also investigate how annealing at 750°C affects the properties, microstructure, and phase composition of the welded joints.
Post-weld cooling rates also significantly influence phase transformation and final microstructure, affecting mechanical properties.
The mechanical properties was determined at normal temperature on the specimens, that were cut from the base and the weld metal.

Nanoindentation has been applied to investigate the mechanical properties of bone tissues.
The mechanical properties of bone tissues were investigated at the microscopic scale in terms of patient age and the correlation between bone mineral density and the mechanical properties were addressed in this paper.
It is worth nothing that a number of factors may affect the measurement accuracy of mechanical properties via nanoindentation.
Hydration is one of the critical factors.
Future studies are needed to clarify the roles played by these factors.

Orthogonal Experiment Factors.
Conclusions VARTM process parameters have a significant impact on the mechanical properties of parts.
So it can greatly improve the mechanical properties of parts.
The greater vacuum is, the better mechanical properties are.
But a long filling time dose not conducive to the improvement of mechanical properties.

Abstract: Curing conditions is one of the most influential factors on mechanical properties and durability of concrete.
The performance of concrete is mainly manifested on its mechanical properties and durability, which significantly affected by raw material, mix proportion and curing conditions.
Compared with the mechanical properties of concrete, curing condition has a much critical influence on the durability of concrete.

Modeling Mechanical Properties of Multilayer Coatings TiAlN Vladimir I.
This work has revealed the effect of Ti/Al ratio on the mechanical properties of multilayer coatings.
Study and purposeful modeling of the mechanical properties of the described coatings are essential for their design due to their dependence on numerous factors.
The mechanical properties of TiN are as follows: Young's modulus – 259 [GPa], Poisson's ratio – 0.25 [6], while the mechanical properties of AlN are: Young's modulus – 273 [GPa], Poisson's ratio – 0.21 [7], .
Thus, the physical and mechanical properties of DLC coatings are inhomogeneously distributed over depth, which will naturally affect the residual stresses both in the coating and substrate, which certainly must be considered in the technology.
