The results of the study showed a significant impact of reinforcement morphology on mechanical properties.
Another study researched the relationship between cooling rate, mechanical properties, and section sizes of A356 [6].
Another study investigated how microstructure coarsening and casting pores affect the mechanical properties of A356-T6 alloy, commonly processed using low-pressure die casting [7].
A modified fatigue model was proposed to address these factors.
The temperature inside the furnace can be controlled by adjusting the varying factors such as voltage, current, resistance, or power supply.

Suspended centrifuge which is the post-treatment equipment during the production process is widely used in the sugar manufacture industry .Sieve basket is the key parts of the suspended centrifuge because its structure, shape and processing property will not only affect the production and use cost of the suspended centrifuge , but also will largely determine the service life of the centrifuge.
The centrifuge used by sugar refinery is mechanical equipment that makes use of the centrifugal force to separate the liquid and solid particles or liquid and the components of the liquid mixture from each other.
We should distinguish the difference of strength standard between the rotary drum and the safe factor.
The centrifugal pressure of filter screen (Pd): use Eq(11) to calculate: The pressure which affects the inner wall is combined material pressure and filter screen pressure.

So as to improve its mechanical properties, the section steel is added in the shaped reinforced concrete columns.
The numerical method was adopted in this article to compile a computer program[3] of full-range nonlinear analysis which can be used for the further research on the mechanical properties of steel reinforced concrete cross-shaped columns (SRCCSC) subjected to biaxial eccentric compression.
Factors affecting sectional curvature ductility Influence of loading angle.
Influence of other factors.
Therefore, the load angle ,axial compression ratio ,the ratio of stirrup spacing and the diameter of longitudinal reinforcement ,are all the major factors affecting the SRCCSC subjected to biaxial eccentric compression, meanwhile, the curvature ductility coefficient and a, n, s / d meet certain numerical relations.

Personal injury and property damage are also serious [1].
The income of constructors (proportion of households, their living expenses), if there were any unpaid wages, their living conditions (including dormitory, food, bathroom, etc.), work time, rest time, contract and medical factors will also affect the safety performance [5].
Table 2 The Classification of Influence Factors Static factors Dynamic factors Work experience Management factors The safety culture of the enterprise The degree of education, the training situation Work environment factors (Dynamically changes - if there's any danger) Economic factors Psychological factors (Mental adventure, self-esteem, etc.)
So in this case, static factors (inherent property of constructors) could be written in the RFID tag.
All the methods above ignore the inherent property of constructors.

But the properties of magnetic levitation components and sensors are limited because of non-perfect property of magnetic material.
Simultaneously, in order to improve machining property of material, the ferrites must be assured of fine mechanical strength.
So it will inevitably affect density and mechanical strength of Mn-Zn ferrites to add NiO.
Accordingly the mechanical strength of ferrite is improved.
According to the Equation of Griffith-Irwin[9], σf = Kc/(π G) 1/2, (1) where σf is bending strength, Kc fracture toughness value and G grain size, porosity and grain size are two essential factors for sharply reducing strength of ferrite.

Different annealing process can deserve different retained austenite content and it can also impact retained austenite morphology, distribution and affect ultimately the mechanical properties of TRIP steel.
These factors play a vital role on the mechanical stability of retained austenite and mechanical properties of TRIP steel.

Mechanical properties and Tensile fracture mechanism of Rheocast A356 Al alloy using Cooling Slope Prosenjit Das*1,a, Sudip K.
Near spherical primary phase in the rheocast alloy ensures better strength, elongation properties and structural integrity in the produced billets.
So, grain refining helps to improve the strength, elongation and fracture properties of rheocast billets further. 1.
The literature available on the topic confirms the effect of microstructural characteristics on mechanical properties and fracture behavior of Al-Si-Mg alloys [5].
Dendritic structure is also responsible for microporosity formation as it creates a solid skeleton within the melt during solidification and reduces its fluidity, which in turn is responsible for air pockets (microporosity) in the solidified ingots and effects the mechanical properties detrimentally.

Introduction Rainfall is an important factor that leads to landslide, according to the statistics about 70% of the landslides are induced by rainfall.
Many scholars have done a large number of researches on the unsaturated soil slope stability under the condition of rainfall, and have achieved lots of important results [1-6], which have a great significance for understanding the mechanical mechanism of rainfall-induced slope instability.
