Milling is one of the most important methods in CFRP mechanical processing.
Additionally, the reduction of tool life due to the inhomogeneous and anisotropic CFRP properties becomes a serious problem.
As expected, the material types of the cutting tools strongly affected their anti-wear performance; in the CFRP milling process, the life performance of PCD tools was relatively better compared to that of WC-Co tools.
This indicates that the wear volume was not the only dominant factor that determined the value of the cutting forces.
A comparing of H between tool II and III demonstrated that H was an important factor to determine the cutting forces; H was larger tool II than tool III, and in agreement with this, the cutting forces of tool II were larger than those of tool III.

There have been numerous studies about the characteristics of frequency and pressure of the Helmholtz-type pulse combustor with mechanical valves or aerodynamic valves.
However, the major bottleneck for popularization and application of the conventional Helmholtz-type mechanical pulse combustors with valves is the self-priming mode of gas supply, which results in lower power operation and narrower range of load regulation.
And assume:①The gases (reactants and products) are perfect. ②The physical properties of the reactants and the products are constants. ③The state variables of the reactants and the products are uniform throughout their volumes. ④No energy losses. ⑤The burning process inside the combustion chamber takes place in a thin zone (a moving flame front) separating a cold zone containing the reactants from a hot zone containing the combustion products. ⑥Continuous supply of gas and air through the orifices and no return. ⑦The tailpipe flow is modelled as a slug flow.

As polymer support was chosen the cellulose acetate due to its natural source [5], high biocompatibility [6], and mechanical properties [7].
As fillers, to improve the separation properties of the pristine cellulose acetate membrane were investigated multiwalled carbon nanotubes, graphene oxide, bone powder and inulin.
This observation can be explained by two different factors.
The small values of retention indicate that the membranes will not affect the proteins equilibrium at the implantation site.

The basic study on the microstructure, mechanical properties, and forming limit of the seamless tube according to changes of forging condition is needed when the seamless tube is formed by applying forging after centrifugal casting.
Therefore, this could affect the gradient of load in the finite element analysis.
A comparison study on the microstructure of specimen with 70% compression at 1100℃ had been shown, and it indicates that the portions in fig.5(a) [A] and [C] were affected by load, and thereby resulted in a narrow grain boundary.
The criteria for fracture in the Cockcroft model are not based on the precise mechanical model and instead recognize the macroscopic role of tensile stress and plastic deformation.

A backward can extrusion test provides severe tribological conditions because high pressure, high temperature, and large surface expansion ratio affect the lubricant.
The test is performed on a 2.5 MN mechanical knuckle-joint press with the initial speed of 200 mm/s for the billet height of 36 mm.
Thus, mc is an important factor when estimating the local radial pressure on the tools and the shape of the workpiece.
In stage 1, the data such as stress-strain curves, strain rate, temperature, mechanical and　 thermal properties, and coefficients of friction mp and mc are input to the FEM calculations.

Introduction Nowadays, materials with special functional properties (also called intelligent or responsive materials) are increasingly used in various industries.
The system-forming elements is Mn (13–35 wt.%) [9] and Si (3–10 wt.%) [10], and additional elements that can improve mechanical properties include: Cr (up to 10 wt.%), Ni (up to 8 wt.%) [11], N (up to 0.3 wt.%) [12], C (up to 0.2 wt.%) [13], V, Mo, Co and others [14].
To create new Fe-SMAs, it is necessary to understand not only how each element affects, for example, the start temperature of the martensitic transformation MS and the temperature of magnetic ordering TN (Néel temperature), but also the technological parameters of the alloy that determine the possibility of its melting and obtaining defect-free ingots, such as liquidus temperature, the possibility of overheating above it, resistance to crystallization cracks, and other.
The loss of manganese as a result of volatilization at high temperatures and in vacuum is one of the key factors causing the unstable yield of usable manganese steels [15].
The calculation for castings with a reduced diameter is based on parabolic time law, linking the thickness of the solidified metal crust with the solidification time using correction factors selected according to the well-known Girshovich-Nekhenzi nomogram, which consider the influence of various technological factors (1) ζ=RτR2amKk2μ confμovμintμgap, (1) where ζ is the thickness of the solidified metal shell at the time τ, m; R is the reduced thickness of the ingot, m; Kk - criterion of the solidification coefficient; am- thermal diffusivity; μconf, μov, μint, μgap - corrections for, respectively, the configuration of the casting, superheating of the metal above the liquidus, for the interval of solidification and the formation of a gap between the ingot and the mold.

It is believed that events occurring at the bone-implant interfaces are influenced by the following material-related factors: implant surface composition, surface energy, surface roughness, and surface topography [4].
Topographical characteristics of a titanium surface may influence not only the mechanical properties of an implant, but also the bone to implant contact rates.
The mechanisms through which the surface properties of the fluorinated TiO2 nanostructured implants improve the osseointegration and new bon formation is currently not sufficiently understood [21].
However, among these nanostructure fabrication routes, the architecture demonstrating the most remarkable properties by far are highly ordered nanostructure arrays produced by anodic oxidation of a Ti alloy in a fluoride electrolyte [15, 25], which the dimensions of them can be controlled precisely.
Conclusion In this study, we demonstrated that the nanostructure formed on SA implant surface was not affected in despite of placement with over torque of 40 Ncm.

Physical properties of the fluid and membrane.
In the study of the 2D isothermal flow, the physicochemical properties of the fluid and the membrane are given in Table 1.
It is observed that the variation of the oil droplet diameter affect the solute concentration.
This behavior is justified by the change in fluid properties that are directly influenced by the temperature variation.
The higher solute retention index the higher the permeation velocity at the membrane surface; d) The increase in the temperature leads to a change in the fluid properties, affecting concentration, pressure and velocity distribution inside the membrane; e) The increase in the temperature inside the membrane causes the accumulation of a greater concentration of solute particles (oil) near the membrane surfaceand reduction in the permeation velocity.

In this article, a regulatory processes study and technological properties of polyamide waste agglomerate modification is carried out.
Despite these promising advantages, polyamide waste recycling can lead to a decrease in its molecular weight [16], which can affect its mechanical properties and reduce its thermal stability, making it more susceptible to melting or deformation and discoloration due to contamination that can reduce the aesthetic aspect of the final product [16, 17].

Due to the factors such as the roughness of the bridge deck, the bridge approach, the interaction between bridge and vehicle defined as vehicle-bridge coupling vibration problem is aggravated.
The coupling vibration is affected by many factors, such as the structure characteristics of the bridge itself, the natural frequency of vibration, the mode of vibration, the roughness of the bridge deck and the pavement, the number of the vehicle’s axle, the running speed, the damping performance of suspension system, the maintenance for the expansion joint of bridge and so on.
Due to its outstanding advantages, this method is widely used in current study. 5 The surface roughness of read The pavement roughness is one of the important factors that affect the coupling vibration of vehicle-bridge system.
For this reason, nonlinear seismic response analysis considering nonlinear properties of these devices will be the direction for further research.
Currently, the mutual mechanism and regularity between structural damage and dynamic properties of vehicle-bridge interaction system, has not caused enough attention and research.
