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.

Abstract: After a number of experiments it was noticed that mechanical vibrations affect the process of austenite on cooling conversion.
Reasons description Inside specialized literature the topic of the thermal-magnetic treatment is quite extensively approached, respectively the effect of the variable magnetic fields on the transformations that occur on cooling, and therefore the effect upon the final mechanical properties [1, 2, 3, etc].
This issue made necessary the deeper study of the factor that may influence the austenite transformation process.
The mechanical vibrations (oscillations) influence the mechanical processes of transformation of the austenite upon cooling. 2.

All the properties values of BIB masonry obtained compared with SB and CSB masonry values.
The masonry units are the main factors that affected the compressive strength of the walls under compressive loads [2].
The features of brick masonry are inclined by the properties of bricks and mortar [3].
In this study, the experimental program involved the preparation of masonry walls for determination of its mechanical properties and the preparation of cube sample for grout and thin layer mortar properties.

Then three profit structure elements: sales volume, price and cost as well as their influencing factors are analyzed, and "profit-elements(-properties)-scheme" is created.
With this model, environment properties scheme is decided to verify its validity and operation simplicity.
Factors affecting price mainly include commodity value, money value and amount, supply-demand relations[11].
Case Study Profit-oriented decision making for schemes of different environmental properties.
Through the above-mentioned three factors, the scheme affects profit directly or indirectly and makes the total manufacturing system be evaluated through single objective, namely enterprise profit.

However, it cannot be removed after high temperature sintering, which will affect the thermal properties of the material.
Because most inorganic binders will not volatilize during high temperature treatment, there will be too much residue in the preform, which greatly affects the thermal and mechanical properties of the final product.
Infiltration temperature is an important factor affecting the interfacial reaction between SiC and Al.
Effect of SiC particle surface adsorbate on the preparation and mechanical properties of aluminum matrix composites.
Microstructure and thermo-mechanical properties of SiCp/Al composites prepared by pressureless infiltration.

In high strength concrete a proper binder content is one of the important factors to have a high compressive strength.
The properties of coarse aggregate such as: water absorption, shape, aggregate strength, and surface texture, play a role in the effect of HSC mechanical properties.

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.

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.

Mechanical properties of adhesive were determined by tensile test and ANSYS analysis.
Mechanical properties for these materials are shown in Table 1.
Therefore, mechanical properties such as Poisson’s ratio and elastic modulus determined.
These mechanical properties are used in finite element analysis.
Thus, the plate 1 was applicable to determine the mechanical properties of adhesive.
