The ability to produce intricate profiles on materials irrespective of the mechanical properties made this process to be widely used in industries.
Nihat Tosun [2] in an attempt to find the effect of cutting parameters on performance of WEDM found out that the significant parameters affecting surface roughness are open circuit voltage and pulse duration.
And the significant factors affecting surface roughness are pulse on-time and open voltage.
In their study, they employed ANOVA to identify the significant factors.
Taking into consideration that peak current and pulse on time are the two most significant factors affecting surface roughness (by ANOVA results), it is necessary to understand their part.

Table 2 presents the mechanical properties at ambient temperature of the samples at different states.
Table 2 Ambient temperature mechanical properties of Al-8.5Fe-1.3V-1.7Si/15vol.
Additionally, stronger particle-matrix bond was a significant factor contributing to the excellent mechanical properties of the composite as rolled after hot pressing.
And the composite sheets of large dimensions and excellent mechanical properties were obtained
The more excellent mechanical properties can be attributed to the three aspects above.

Mechanical performance such as the bending strength and fatigue characteristic of this expansion joint in addition to the basic properties of epoxy resin mortar was clarified.
The basic property of epoxy resin mortar used for the joint and the mechanical properties of the flat panel of UHSFRC were researched.
Thus, the sealant of expansion joint is an important part of a necessary effort to prevent negative external factors from affecting the life time of newly constructed and existing bridges.
The physical and mechanical properties of the epoxy resin mortar are shown in Table 1.
Figure 10 The load steps at the static cycle load test Figure 11 The view of pavement on the joint just after construction and 22months later Conclusion Mechanical and physical properties of a newly developed advanced buried expansion joint composed of ultra high strength fiber reinforced concrete, epoxy resin mortar, and elastic sheet were investigated by loading tests and field experiments.

Before mechanical analysis of the reinforced concrete single T-shaped beam, mechanical parameters must be held and input.
Whereas, it is fairly difficult to grasp mechanical parameters exactly.
The mechanical parameters are often determined by experiments, which cannot take the influence of concrete factors into account and cannot accurately reflect the factual circumstance [8].
Bayesian parametric back analysis estimation is a theory that when the conditional distribution of the measuring displacements and the pre-testing distribution are given, the statistical properties of mechanical parameters are the needed quantity only if the post-testing distribution gets its maximum.
The iterative process of stochastic Gaussian optimal inversion of mechanical parameters of the reinforced concrete single T-shaped beam is steadily convergent to the same values and the convergence property of mechanical parameters is not affected by the number of random variables.

However, these models do not pay attention to the mechanical properties of concrete after carbonation.
For example, concrete constitutive relation after carbonation, the mechanical properties of concrete after carbonation, and so on.
Secondly, they study the mechanical properties of concrete materials affected by the pure sulfate or chloride chemical attack and also analyze the changed rules of the elastic modulus and other mechanical index and the micro-mechanism of concrete deterioration.
The method, multi-index weighted grade durability evaluation method, considers fully the various factors affecting the durability.
Many factors affect the structural durability.

THE WELDING PARAMETERS SUCH AS WELDING CURRENT, FORCE, WELDING SPEED, AND FILLER METAL WILL DIRECTLY AFFECT THE MECHANICAL PROPERTIES AND MICROSTRUCTURE OF THE WELDING JOINT.
These standard arrays will provide complete information about the factors and their influence on the efficiency of the process.
The orthogonal arrays utilized in the experiment were chosen from the orthogonal arrays determined by the number of factors and their levels.
On the other hand, welding joints are formed on the surface of two materials with different chemical and mechanical properties.
The degree of influence of each welding technology parameter on two mechanical properties are: bonding strength and microscopic hardness of the weld have been determined.

The intertwining action of the hyacinth fiber on the mechanical properties of pellets was investigated.
The negative effect of elastic recovery on the other mechanical properties of pellets should be evaluated.
By comparing the mechanical properties of H/S-BPs to S-BPs from Fig. 1 and Fig. 3, we can found that the mechanical properties of H/S-BPs were better than S-BPs.
