To sum up, because of many factors affect rock burst,So far it is about its formation mechanism of knowledge has not unified.The mechanism of rock burst from mechanical characteristics in terms of research can be divided into the statics mechanism and kinetics mechanism.Judging from the rock burst damage form into shear failure and tension destruction.
From that strength theory formula, it basically is to consider is the rock mechanics properties and geostress relationship, Expression is simple, and in engineering achieved certain achievements.
Therefore the forecast to rockburst comprehensive multiple factors were discussed, The author thought that rock properties of rock burst have decided the internal and external environment conditions and the external disturbance, so for several main consideration rockburst forecasting core theory is strength theory, energy theory, stiffness impact theory, most other theory is the extension of three theories or developing.
On rock burst intensity the probability of occurrence in statistical forecasts, only a few researchers use single factor index of a simple predictions, not fully consider other factors affect rock burst, has some limitations and one-sided
But many factors affecting internal links without a simple formula, therefore can not be calculated using artificial directly.

The mechanical properties of parts obtained by the FDM method mainly depend on production parameters, such as print temperature, print speed, scan path, nozzle diameter, layer thickness, chamber temperature, and fill factor [29].
It is known that a higher or lower printing temperature, layer thickness or printing speed can lead to deformation of the sample, which directly affects the operational properties of the final product.
The authors of [37] investigated the effect of temperature, printing speed, filament layer thickness, and fill factor (Table 1) on the mechanical properties of PEEK.

Analysis of Influence Factors for White Layer in Grinding of Harden Steel Xiangming Huang 1,a, Zhixiong Zhou1,b, Yang Jun 1 and Qilong Xia1 1 College of Mechanical and Vehicle Engineering, Hunan University, Changsha, China, 410082 ah_xiangming@yahoo.com.cn, bzhouzx@sina.com Keywords: Grinding process, White layer, Harden Steel, Influence factors Abstract.
Thus, white layer formation is one of factors that affect product performance.
Some studies have shown that process parameters affect the formation of white layer.
Eda [6] studied white layer properties on a machined surface of harden steel when a large depth of cut and higher feed speed were used.
However, the above studies concentrated on the properties of white layer and the formation mechanism of ground white layers, a systematical analysis of the effect of grinding parameters on white layer has not been carried out.

Factors affecting machining performance Electric Discharge Machining (EDM), Laser Beam Machining (LBM), Ultrasonic Machining (UM) and Abrasive Water Jet Machining (AWJM) are the unconventional processes usually deployed for machining the NFRCs.
Considering all the above-mentioned factors, AWJM could be chosen as the best candidate for machining composites as they no longer need to be conductive, less heat affected zone is produced and generates no fumes.

The interface zone in concrete is the weak link and its structures and properties are the key factors determining overall performance of concrete.
Introduction With the development of the more and more high strength and performance concrete, the interfacial properties between aggregate and mortar turn into the weakest links deciding the concrete mechanical performances[1-3].Concrete properties relates to a great degree to structures and performance of ITZ.
In these experiments , specimens interfaces was polished to be unlike to the actual structures and properties of the aggregate-mortar interfaces so that they couldn’t respond real strength as well as influences of the aggregates sizes.
With the increase of particle size of pebbles and projective areas, macro pull strength of the interfaces are affected by the strength of concrete.

Mass segregation of Al2O3 slurries during centrifugal slip casing has important effect on microstructure and mechanical property of sintered Al2O3 ceramic, so the study on effect of centrifugal process parameters on mass segregation of slurries has significant meaning.
Introduction Alumina has several special properties like high hardness, chemical inertness, wear resistance, and high resistance to thermal and corrosive environments, which are widely applied in the fields of mechanical engineering, electronic technology, chemical engineering and biological engineering [1-4].
However, with the difference of fabrication process, microstructure and mechanical property of Al2O3 ceramic are different.
However, mass segregation of slurries came from particle size difference in the initial powder is obvious during centrifugal slip casting, which can affect the microstructure and mechanical property of sintered Al2O3 ceramic.
In a monolithic system with low solid content, the following second-order differential equation is obtained to describe the particle movement using Newton’s second law: (4) Integration of Eq.(4) over time t results in [6]: (5) In slurries with high solid content, v is corrected by the correction factors h(φ) [7] (φ is solid content of slurries) and is expressed by: (6) As can be seen in Eq.(6), the settling velocity of Al2O3 particles can be affected by particle size, acceleration and solid content of slurries.
