Experimental Study on High-speed Milling of SiCp/Al Composites Yingfei Ge1,a, Jiuhua Xu2,b and Yucan Fu2,c 1Jiangsu Province Key Disciplines of Mechanical Manufacture and Automation, Nanjing Institute of Technology, Nanjing 211167, China 2College of Mechanical & Electrical Engineering, Nanjing University of Aeronautics & Astronautics, Nanjing 210016, China ayingfeige@163.com, bjhxu@nuaa.edu.cn, cyucanfu@nuaa.edu.cn Keywords: Particle reinforced aluminum matrix composite, High speed milling, PCD tool, Machinability Abstract.
Introduction Particle reinforced metal matrix composites (PMMC) possess many outstanding properties such as high specific stiffness, high wear resistance, low density, high thermal conductivity, low thermal expansion, low fabrication cost, easy shaping etc.
Volume fraction, average size of SiC particles, tool grain size, coolant and heat-treatment have significant influence on the tool wear (comprehensive analysis of the tool wear mechanisms and the influence factors will be presented in detail in another publication).
However, the waves produced by the periodic feed of the tool nose were the most important fact that affected the surface roughness profile.

The manufactured heat exchanger was visually evaluated for defects that could affect the functionality of the element.
This fact allows for the economical production of mechanical ventilation equipment including heat exchangers made specifically for a given room and a given number of air changes per hour.

During the deformation process at high temperature, large number of mechanical work is converted to heat energy by means of large plastic deformation and friction force between die and work piece.
Related with many factors, these interface coefficients are very difficult to be directly measured [8-10].
This method needs many passes, and the properties of this integrated structure are poor.

These temperature rises may affect the microstructure of the forging.

It then addresses how fatigue load affects the bond between FRP and steel.
The conventional fracture mechanics theory was extended to predict the FRP strengthened steel plates by considering modification to the stress intensity factor and stress range due to FRP [42].
The effect of different parameters such as the prestressing level, steel grades and geometric and mechanical properties of the plate on both the interfacial shear stress and the flexural behavior of the plated beam were discussed.
Their results from both theory and experiments showed that although the geometric and mechanical properties of the FRP plate have influence on the stiffness and the yield load capacity of the plated beam, prestressing does not affect the stiffness of the plated beam but increases the yield load capacity.

Their optical, electrical, magnetic, physical and chemical properties differ significantly from those of bulk materials [2].
Various factors are known to influence nanoparticles synthesis.
Beyond a silver nitrate to plant extract ratio of 4:1 probably other factors like site saturation would explain why AgNPs production at higher ratios would be lower.

The Revelation Research of Folk Paper-Cut Creation Concept on Modern Product Design Yuanyuan Zhao *, a, Liling Chen b, Suihuai Yu c, Junxuan Chen d Department of industrial design, School of Mechanical Engineering, Northwestern Polytechnical University, Xi'an Shanxi, China a965328981@qq.com, bcllzsh@126.com, cysuihuai@vip.sina.com, d243348957@qq.com Keywords: Paper-cut art, Concept of creation, Product design Abstract.
In the folk paper-cut art creation process, the folk artists have completely copy the real image, and generalize the main characteristics of the object, which often needs to create refined, simplified, and in this way, the theme can be highlight, and the interference of other unnecessary factors was also reduced .
In biology concept, "gene" is the material basis of heredity, and the "cultural gene" is an inherent property of a certain kind of culture hidden, inherited down with its unique context, with a distinctive cultural characteristics.
The aesthetic standards of modern simplicity natural to some extent affect the design itself, since twentieth Century, minimalism emerged in Sweden, and rapidly spread to the world, it is coincide with Chinese classical artistic conception which is called "The great form has no shape" and Zen thought called "the best way to simple" .

Introduction Crash safety of automobile has become one of the research focuses the last decade in the field of automotive passive safety research [1], especially the coach, which result in the casualties and property damage will be enormous in the event of traffic accidents for its large capacity and high usage.
Establishment of finite element model Firstly, considering the size, accuracy, and computer, the prototypes is reasonable simplified without changing its basic mechanical characteristics.
Excessive acceleration is the main factors caused the occupant injuries in the collision.
Through the mounting bracket can be connected with chassis frame by welded or bolted directly, which does not affect the approach angle and ground clearance of the coach.

Numerical Modeling of Fire Dynamic Behavior for a Five-Story Building Cherng-Shing Lin1*, Te-Chi Chen2, 1~2 Department of Mechanical Engineering Yuan Ze University, Taiwan 32003, R.O.C email： mecslin@saturn.yzu.edu.tw Keywords: particles, stack effect, smoke diffusion, numerical model Abstract.
According to statistical information shown in Table 1, major fire accidents have occurred frequently at public recreation venues throughout the country over the past several years, resulting in significant losses of life and property.
Because of numerous factors such as improper zoning of sites, the use of inflammable materials in decorations, blocked building evacuation passages, and business owners’ ignorance of fire safety measures, when fire accidents occur, deaths or serious injuries usually result.
Some people fled toward the third floor only to become affected by the pervading smoke particles, declining layer, and decreased visibility; therefore, they were unable to discern the correct direction for escape.

Introduction: Inadequate access to clean water and sanitation has been one of the most pervasive problems affecting people throughout the world.
The key parameters affecting the disinfection efficiency in terms of the reliable life (tR value) of this model were studied.
The calcination atmosphere strongly affected the composition, structure, and optical and antimicrobial properties of TiON nano-particles.

The drilling process itself always generates unwanted residual stresses due to thermo-mechanical effects of the cutting process [3, 4].
Materials and procedures Two aluminium alloys presenting different mechanical properties were selected for this study: a 5083 aluminium alloy, having magnesium as main alloy element and a 7022 aluminium alloy, having zinc as main alloy element.
Table 1 shows the main mechanical properties of both alloys.
Mechanical properties of the aluminium alloys Fig. 2 Specimens’ geometry (left) and strain measurement directions using an ASTM A rosette (right) For the tensile calibration tests, during the experimental phase, a Monsanto tensometer was redesigned and adapted to perform the tensile tests horizontally, providing enough space for specimen assembly and drilling.
However, a scale factor should be taken into account, since in this case the strain relaxation due to hole-drilling is related to a greater calibration stress.
