The cutting efficiency is directly affected the construction of petrochemical and nuclear power.
For many difficult materials cutting technology, the selection of processing technology is most important among of factors of affect processing cylinder efficiency [1].
Ordinary cylinder hundreds of tons, hydrogenation reactor, up to 1000 tons more; Outer diameter of over 5m(Fig.1);Rough surface, severe calcification, These factors lead to large depth of cut when cutting, More cutting removal (removal of 25%), low cutting speed, feed rate is slow and so on.

The FCG depends on several factors such as stress intensity factor (K), crack length (a), number of cycles (N), stress intensity factor range (del K), load (P), frequency (f), and stress ratio (R).
The empirical modelling considers the crack driving forces/factors and develops an empirical solution while considering various factors for crack propagation [6].

This manufacturing process allows for precise control over the microstructure of the steel, leading to improved mechanical properties and performance.
The basic mechanical properties of the obtained materials are shown in Table 2.
These inclusions lead to local stress concentration, inducing crack nucleation and propagation near the region, which is a key factor affecting the fatigue impact life.

The ITZ (interfacial transition zone) in concrete has very high porosity and permeability, which affects concrete’s macroscopic mechanical properties and transport properties.
In addition, some scholars hold that the thickness t depends on the properties of the cement particles [5-8], which implies t should be uniform.
Zhu and Chen et al.[11,12] studies how aggregate’s particle size distribution (PSD) and shape affect the misestimation of t induced by 1D linear analysis.

By summarizing the 3D deformation regulation of the hot extrusion centrifuge pipe mould, the stress changing and mechanical property parameters during the process of hot extrusion , providing reference for the design of equipment in radial hot extrusion.
However, it is difficult to find an effective solution to the main mechanical properties through formula and experiment.
The real extrusion of mould deformation will affect the size of extrusion stress.
Of course, the results difference between simulation analyses and the real state will occur by material properties error.
Other influencing factors to error results during in simulation analysis process: (1) The quality of mesh division influence precision of solving; (2) Some assumptions that are made in the numerical simulation, such as supposing the temperature of the deform body remaining constant have certain difference with the actual operating mode; (3) Some geometry was simplified, such as chamfers and arcs are neglected for the mesh.

However, Ti50Ni10Cu40 alloy strip was so brittle that its mechanical properties could not be measured.
The mechanical properties such as elongation and stress hysteresis were also determined in as-cast strips of Ti50Ni15Cu35.
However, the mechanical properties of Ti50Ni10Cu40 strips could not be analyzed in this study because of their brittleness resulting from the excessive Cu-contents.
Even though the most important factor affecting on the shape memory characteristics of Ti-Ni-Cu alloy is Cu-content, it was reported that the large transformation strains (compared to those of ingot materials) were obtained due to the texture of the heat-treated ribbons [10] and the small hysteresis was also obtained due to small grain size of the melt-spun ribbons [11].
Summary Microstructures, transformation behaviors and mechanical properties of Ti50Ni15Cu35 and Ti50Ni10Cu40 alloy strips fabricated by the arc melt overflow process have been investigated.

Two-phase Flow (Oil-Water) in Petroleum Reservoir with Irregular Geometry Including Water Injection: Effect of Porosity on the Oil Recovery Factor F.
To produce oil as efficiently as possible is important to understand the distribution of the fluid, as well as the properties of the reservoir at any time during the production process.
By comparison the cases of Table 1, one can see that by increasing porosity, the pressure difference between the producing and injection wells are affected.

These coatings can significantly enhance properties of structural parts such as thermal and wear resistance or fatigue life.
The fatigue properties are influenced by the nature of the deposited coating (modulus, microstructure, porosity etc.) and by residual stresses introduced to the substrate during spraying and associated preparation steps such as grit-blasting.
Prior to testing, surface of metallographic cut was electro-polished in 5 % perchloric acid solution in ethanol at 40 V to avoid the surface layer affected by mechanical grinding and polishing.
The BS signal represents electron backscattering pattern (EBSP) quality factor derived from the Hough transform that describes the maximum intensity gradient at the margins of the Kikuchi bands in an EBSP.
In comparison with nanoindentation, this technique has higher spatial resolution (due to the use of the electron beam) but it is not directly related to the material (mechanical) properties.
