The tensile properties, particularly Young’s modulus and elongation at break, were evaluated based on the stress-strain behavior of the tested specimens.
Table 1: The L27 Taguchi orthogonal array Results and discussion ANOVA was conducted to determine the statistically significant parameters that influence the tensile properties of PA66-GF gears as well as to identify the percentage contribution of each control factor during the injection molding.
Based on the ANOVA results, blending ratio and melting temperature are considered as the most significant factors affecting the Young’s modulus.

In addition, these microPCMs possess properties of thermal stability, high mechanical strength and high surface area during a thermal transmission process.
It can be imaged that the encapsulated PCMs characteristics, microPCMs shell properties (thickness, intension and average diameter), matrix and the interfacial adhesion structures (microPCMs and matrix) are four main factors affecting the interfacial stability of microPCMs/polymer composites.
The microPCMs with MMF shells have enough mechanical properties to resist the internal stress.
And these interface changes will affect the mechanical properties of these microPCMs/polymer composite in application.

The study has examined the influence of FSSW (friction stir spot welding) parameters (rotation speed, downward compression and welding period) on mechanical property (shear resistance force) by conducting FSSW experiments on 3mm-thick AZ31 magnesium alloy plates under the orthogonal design.
Microstructure observations show that tiny and even equiaxial grains are formed in WN (Weld nugget zone) and coarse grains with uneven sizes are formed in TMAZ(thermo-mechanically affected zone) and HAZ (Heat affected zone).
This paper describes the experiment and analysis of FSSW for welding of AZ31 magnesium alloy as well as the mechanical property and microstructure of welded joints and obtained optimum welding parameters.
Please refer to Table 2 for factors that influence the experiment index and their levels and this is an orthogonal experiment with three factors, three levels and one index.
Hence, among parameters in this experiment, factor B (welding period) is the major factor deciding the shearing resistance force of joints, factor A (stirring head’s rotation speed) and factor C (downward compression of shaft shoulder) are secondary factors.

Formation of the Surface Layer Properties in Edge Cutting Machining of Stainless and Heat-Resistant Steels Dmitriy V.
Abstract: The article considers features of a cutting process of stainless and heat-resistant steels and factors that determine difficulties in machining these materials.
Though heat-resistant and stainless steels differ from each other, they have a number of common physical and mechanical properties that determine their common technological properties with respect to machinability by cutting.
The worst machinability of these steels and alloys is determined, first of all, by the structure and mechanical characteristics that determine their properties not only in the initial state but also in the hardened state and under heating, as well as by the thermophysical parameters (melting temperature, activation energy and thermal conductivity) that determine properties of material at elevated temperatures.
Thus, the properties of the material machined largely determined the features of the chip-forming process and, consequently, wear of the cutting tool and formation of the quality of the surface machined.

Analysis on the Influence of O-MMT in the Properties and Bacterial Count of PVDF Nanocomposite Membrane Acelle Pearl T.
Analysis of the study further showed other factors that needs to be accounted since they were observed to highly affect the structure and properties of the membranes.
Whilst PVDF acts as the matrix of this study, it has been observed that the introduction of fillers to the polymer matrix improves the various properties without affecting their processability[2][9].

Water in liquid and gaseous form is the main factor which significantly affects degradation processes in the wood.
This article presents results of the experimental study that deals with the mechanical properties of bonded joints in the wood treated by silicones.
Even some other studies [8] show that the adhesive joints in the modified wood may show different mechanical properties depending on the type of adhesive used or environmental effects [9].
The depth of the intersection, respectively the depth affected by modification depends on several factors, e.g. on species, steep time, etc.
