In recent years, hidden frame curtain wall problems such as glass spontaneous breakage, drop and structural sealant ageing caused number of personal injuries and property loss.
Besides the ageing research, Vallabhan etc [5] pointed out the size and material properties of the silicone sealants affected the efficiency of the structural glazing system.
Influence of Structural Sealant on Mechanical Behavior of Glass Panel.
The adhesive width variety could not affect the fundamental mechanical behavior of glass panel in hidden frame curtain wall.
Actual project could choose whether or not increase the adhesive width through weigh and balance the economic factors and curtain engineering quality. 5.

This article aims to study the NiTi shape memory alloy wire’s constitutive behavior coupled thermal and mechanical properties at different temperatures.
Thus, the temperature is an important factor affecting the mechanical properties of shape memory alloys [8].
It is difficult to describe the NiTi shape memory alloy’s constitutive relationship, because of its special and complex mechanical properties.
By analyzing the results of experiments, the mechanical properties with the changes of each major factor will be studied. 2.
This indicates that memory alloys and ordinary metals exhibit the same basic mechanical properties.

High-speed steel is characterized by excellent mechanical properties, high hardness and impact resistance, good fracture toughness and fatigue resistance.
Therefore, special attention is paid to important factors that affect the qualitative and quantitative indicators of the machined area.
Their size and shape depend on a large number of factors.
Basically, it is the chemical composition and physical properties, such as the size of the wire cross-section, shape, composition, composition, geometric accuracy, or the mechanical properties of the wire material itself, which primarily represent ductility and strength, determining the limit of the maximum tension of the wire by force in a given diameter [18].
This would lead to an increase in cutting performance without affecting the quality of the machined surface. 3 wire tool electrodes were used in the experiment.

Many factors such as vibration, environment temperature and air cleanliness should be considered when fabricating precision components.
Both dynamic error and sliding error are important factors which should be considered in the profile error compensation of FTS diamond turning process [8].
It improves the properties and the performance of surfaces [9].
Some of the important factors, such as the cutting force, cutting edge radius, cutting fluids and the speed of spindle, should be taken into account while selecting cutting parameters [11].
In UPRM, the factors are much more complicated in affecting the quality of surface.

The pulse duration is significantly affecting the EWR.
Nickel based super alloy, Inconel 718 is an aerospace material and considered one of the most difficult-to-machine material which attributed to its ability to maintain hardness at elevated temperature, very poor thermal properties, high toughness, high hardness, and high work hardening rate and consequently it’s very useful for hot working environment.
Copper became the metallic electrode material of choice for EDM even though it wear rate is higher due to the melting point temperature of copper is low but copper have high in electrical and thermal conductivity properties.
The formula for duty factor is stated in Eq. 2.

Abstract.
Surface appearance of the thin film (a)1Cr18Ni9Ti (b)Ti Because 1Cr18Ni9Ti stainless steel is a kind of alloy material, the consistency of the composition between the film and the target is an important factor that affects the property of the film.
There are multiple factors of sputtering technology parameters can affect the adhesion between films and substrates.
Film adhesion is affected by the multiple factors of Van der Waals force, diffusion, mechanical lock, electrostatic attraction and chemical synthesis influence.
From the above analysis, it can be seen that the film adhesion is affected by the multiple factors of sputtering time, sputtering power density and target materials.

This is a relevant situation related to economic factors, energy consumption and productivity involved in the manufacture of composites [1].
In spite of the technological attractiveness, none of these methods guarantee the mechanical properties of the composite due to the relatively long time (6 min to one hour) of sintering operation.
It was found that temperature and pressure are not the only factors to ensure the initial quality of the precursor diamond powder, the sintering time is also important.
The actual difference of about 50% indicates that other factors in the composite do not allow the Rule of Mixture [10] to be used.

Concrete has remarkable fire resistance properties.
Mechanical properties of concrete such as compressive strength and modulus of elasticity are greatly reduced during exposure to fire.
Scope Cement mortar undergoes significant changes when exposed to high temperature: as a result, the mechanical properties of concrete are affected by high temperature, and the behaviour of structural members may differ from the original design after being exposed to fire.
An admixture consisting of zirconium oxide and titanium oxide may affect concrete properties in different ways, depending on the percentage of admixture.

Appraisal of threshers
The factors influencing the levels and rates of performance of threshers can be grouped into crop
factors and machine factors.
The crop factors are moisture content of the grain, variety of crop, method of drying after harvest, density and specific gravity, shape and size of the grains and strength of the grains.
Materials and Method Before the design and development of the thresher some physical and engineering properties of the cowpea pod were considered.
