The surface morphology, the etching products and the mechanical properties of the fine NiTi wires after the chemical etching process are investigated in the paper.
Mechanical properties of NiTi alloy fine wires after etching were studied by means of tensile tests.
Then, measured hardness values are considered hardly affected by superelasiticity[3].
The main influential factors for mechanical properties are the local stress concentration caused by surface corrosion pits.

Introduction The prediction of the mechanical properties of composite materials can improve the testing efficiency of the mechanical properties of composite materials, which is of great significance to the testing of the mechanical properties of composite materials.
The mechanical properties of the materials refer to the macroscopic mechanical properties of materials at the room temperature or under the static load.
The prediction model of the mechanical properties of composite materials can be established through considering the composition of materials, the manufacturing processes, the environment and other relevant factors.
The prediction model of the mechanical properties of composite materials has played a guiding role in the testing of the mechanical properties of the composite materials.
In short, the mechanical property of the composite materials is the nonlinear model that is affected by various relevant factors.

In conclusion, the incorporation of vanillin into PMMA resin could affect its mechanical properties.
In addition to the antimicrobial properties, the mechanical properties of the appliance are crucial criteria to utilize in clinical uses since a lack of these properties can reduce the appliance's functions and can cause major complications.
A mechanical property evaluation is needed to confirm sufficient properties.
Theoretically, many factors influence the mechanical properties of the resin, such as chemical composition, curing method, degree of polymerization, and storage [10-12].
Summary This study demonstrates that incorporating vanillin into PMMA resin causes a decrease in its mechanical properties.

The mechanical properties SLA 3D printed parts are not yet determined or estimated before printing.
Sagias et al. determined the influence of printing factors in obtaining improved mechanical properties of a 3D printed material printed through Fused Deposition Modeling (FDM) with Acrylonitrile butadiene styrene (ABS) as feedstock.
Based on Taguchi’s methodology, the standard arrays called Orthogonal Array specify which methods are needed in finding the minimum number of experiments that can provide the full information to all the factors such as Layer Thickness, Orientation, Curing time and Curing temperature which are directly affecting the 3D printed material.
For this study, the identified controllable factors according to the influence on the hardness properties of the 3D printed test block are: Layer Thickness, Orientation, Curing Time, and Curing Temperature.

The mechanical properties of B4C-CeB6 composite prepared by hot pressed sintering method were tested.
Lots of boron carbide composites have been studied in order to enhance its properties and improve drawbacks of B4C.
To the authors’ knowledge, there is no publication available on Mechanical properties and fracture mechanism of B4C-CeB6 composite [5-9].
Flexibility strength is affected mainly by two factors of porosity and grain size.

In terms of mechanical properties of composites with natural fibers, both fiber loading and their orientation in the matrices are important factors.
In this research work, the effects on the mechanical properties of reinforcing quasi-unidirectional salago fiber in epoxy resin were investigated.
In the case of natural fiber reinforced composites, the major factors that can affect their mechanical properties include the type of fiber and matrix materials, the orientation and dispersion of natural fibers, the adhesion or interaction of the fibers to the matrix, the processes involved in the composite fabrication and the void fraction [3].
Similarly, in a study about bi-directional jute fiber composites, better mechanical properties were obtained at higher fiber loading [6].
Aside from fiber content, the length of the fiber can also affect the mechanical properties of fiber reinforced composites [7, 8].

Four factors investigated were amount of UVabsorber, antioxidant, carbon black, and flame retardant.
The amount of UV-absorber and other additives seemed to exhibit significant interaction effect on mechanical properties.
