The properties and the performance of Thermally Stable Diamond Composite (TSDC) directly affect the applications of TSDC in engineering.
The failure risk of the TSDC cutting tips during a cutting process is affected by many factors, including the Depth of Cut (DOC) of the pick with the TSDC tip.
The failure risk of the TSDC tips is significantly affected by the various uncertain factors in the mining environment, including the TSDC material properties, TSDC tip shape and size, rock strengths, the angle of resultant force (or simply resultant angle) on the tips and the Depth of Cut (DOC).
DOC and resultant angle of the resultant force are two major factors that directly affect the characteristics of bending force on the tip in the mining and construction industries.
To strength the study, the impact of the uncertainties in other factors will be analyzed in the future.

Metalloscope results also showed that
microscopic structure of different specimens with different thicknesses is also a factor affecting the
fracture toughness.
For example, Arzt et al have demonstrated that size effect on the material properties of foil materials was attributed to dimensional and microstructural constraints [3].
Yoonjoon et al analyzed size effect on the mechanical properties of thin polycrystalline metal films, and developed a model that correctly predicts the observed influence of film thickness and grain size on stress evolution during thermal excursions [4].
The major factors affecting these two contributions are considered to be related to the combined action of the microstructure, the presence of inner micro-defects and roll marks, and the level of stress triaxiality.
Thickness of V Specimen 2, conclusion can be drawn that the microscopic structure of materials as well as thickness is one main factor affecting the fracture toughness.

The ideal semisolid slurry with homogeneous spherical and fine primary crystals could be obtained by optimizing rod insertion temperature, rotation speed and its diameter, which is a key factor in semi-solid forming.
The thicker components produced by the process exhibits better mechanical properties than those by conventional casting[3,4].
It can be seen that the time interval from rod insertion start to insertion end affected the distribution of the primary spherical crystals.

In the process of removing wrinkles, possible related factors can be divided into two aspects.
The mechanical properties of fabrics that are associated with fabric movement include tensile and shear properties, bending, compression, surface characteristics, stiffness, fabric weight, and thickness [1].
Raja Zaoual obtained that fabric composition, weight, drape coefficient, fabric structure, warp and weft density and twist of fabric are the main factor affecting the performance of fabric wrinkle [3].
Therefore, the wrinkle recovery rate can be used to represent the comprehensive physical and mechanical properties of the fabric.

That is to say, there is effect of environment on the mechanical properties of the alloy.
Therefore, it was inferred that the effect of tensile environment on the mechanical properties of the alloy is actually the effect of hydrogen in the environment on the mechanical properties of the alloy.
Fig. 4 The mechanical properties of FeCoNiCrAl0.1 alloy tested in various environments.
On the other hand, the effect of hydrogen on the mechanical properties may be related to hydrogen affecting the formation and diffusion of vacancy.
There is obvious effect of tensile environment on mechanical properties of FeCoNiCrAl0.1 alloy.

The paper presents an overview of “lessons learned” with detailed information on factors affecting the rate of chloride ingress.
This paper presents an overview of “lessons learned” with detailed information on factors affecting the rate of chloride ingress and the performance of concrete containing supplementary cementing materials (SCM) such as fly ash, ground granulated blastfurnace slag (hereinafter referred to as slag) and silica fume.
Examination of the concrete after exposure revealed that the air-void spacing factors were good (generally ≤ 230 microns) and that there was no evidence of micro-cracking related to freeze-thaw damage.
This indicates that damage was, generally, restricted to the surface and this explains why the bulk properties of the concrete, as measured by UPV and RDM, were unaffected.

Abstract.
The typical objective of coating is to improve the appearance and printing properties of paper.
The coating structure and surface topography are dependent on factors such as pore structure, coating color formulation, particle arranging,coating speed and drying temperature, et.
The amount and type of latex binder, pigment particle size, and coating condition have a significant effect on both the structure and chemical properties of pigment coatings, which affects critical surface properties, e.g., gloss, ink setting rate via liquid absorption, and spreading properties [4, 5].

The
calculation results show that the length and the diameter of SWCNTs are relatively significant factors
affecting the buckling behavior of SWCNTs.
Introduction Ever since the discovery of carbon nanotubes (CNTs) in 1991 [1], more and more studies are focused on their excellent mechanical properties.
The defects affect the mechanical behavior of CNTs.
For the mechanical properties of CNTs, the buckling behavior has been studied by molecular dynamics simulation (MDS) [2], continuum mechanics models [3] and molecular structural mechanics [4].
The wall thickness is 0.34 nm and the elastic properties are referred to [6].
