Test Study of Fracture Mechanical Properties of Reactive Powder Concrete with Additives Zhigang Yin 1,2 1.
Fracture mechanical properties of RPC is researched in double-K fracture model and fracture energy release rate G.
What people concern currently is the study on the preparation of high strength and performance concrete as well as its tensile strength, compressive strength and other mechanical properties; while the study about the mechanical parameters, such as fracture mechanics properties (fracture toughness, fracture energy) and the durability affecting the structural use is relatively less, so it is necessary to conduct further research.
Mechanical properties of reactive powder concretes.
Preparation technology and mechanical property test research of Reactive Powder Concrete.

The curves of each factor and lever affecting comprehensive properties were drew through the orthogonal design L9 (34) experiment.
The effect of each factor and level on the comprehensive properties is as Fig. 2.
Fig.2 The curves of each factor and lever affecting comprehensive properties We can know from Fig.2 when freeze temperature is -20 ° C; ammonia content is 0.1 ml; KGM content is 2g and HAPw content is 4.5g, the comprehensive property scores of the scaffolds reach the maximum.
The hydroxyapatite whiskers exist in the pore walls of the KGM alone and do not form any bond with KGM so the hydroxyapatite whiskers improve mechanical properties of the composite scaffolds unobviously.
The optimal preparation program of the scaffolds is determined as: KGM (2g), HAPw (4.5g), ammonia (0.1 ml) and the freeze temperature (-20 ° C) based on the orthogonal design L9 (34) experiment and the curves of each factor and lever affecting comprehensive properties.

Atomistic Scale Modeling of Factors Affecting the Channel Mobility in 4H-SiC MOSFETs Aveek Chatterjee1,a, Asha Bhat1,b and Kevin Matocha2,c 1 GE Global Research Center, 122 EPIP, Whitefield Road, Bangalore-560066, Karnataka, India. 2 GE Global Research Center, One Research Circle, Niskayuna, NY-12309, USA a aveek.chatterjee@ge.com, basha.bhat@geind.ge.com, cmatocha@research.ge.com Keywords: Silicon Carbide, Surface energy, Molecular Dynamics, Defects, Screening distance Abstract.
It is expected that the interface defects and near interface defects in SiO2 will affect the inversion channel mobility significantly.
Section 2 elaborates the computational methods, which have been used to analyze the surface properties of SiC and the screening distances of defects in SiO2 and SiC.
The simulation results corroborate the fact that the physical properties of duplicate crystal planes are similar.
Also, the crystal plane with lower number density of atoms (atoms/cm2) will endure lower mechanical stress after oxidation, which in turn will lead to lesser interface defects.

Study on the Stress Intensity Factors of Double Cracks Normal to and Dwelling on the Interface in the Cladding Material Structure Yang Junrua, Chen Gonglingb, Zhang Lilic, Sun Jingd College of Mechanical and Electronic Engineering, Shandong University of Science and Technology, Qingdao, China, 266590 ajryangzhang@163.com,bchengl6@163.com,czhanglitqd@126.com,dsj_sdust@126.com Keywords: Cladding Material Structure, Double Cracks Normal to and Dwelling on the Interface, Stress Intensity Factor Abstract: Based on the theoretical study on the tip stress intensity factor (SIF) of the crack normal to and dwelling on the interface, using the finite element software ANSYS, the SIFs of the double interface cracks normal to and dwelling on the interface in cladding material structure are studied by changing the crack spacing, the crack length, the cladding thickness ratio, the load and the crack location.
For the double cracks normal to the interface in layered piezoelectric material, Zhengong Zhou used Schmidt method to study the static problems of the double cracks under the anti-plane load, and found that the SIFs had relations with the crack length, the electrical load, the layer thickness and the material properties [4].
The material property parameters are shown in Table 1.
When the lower crack goes farther away from the boundary, it is affected by the boundary more slightly, and the SIF become smaller.

Drum Sludge Drying Equipment Energy Dissipation Factor Analysis Xiaolu Ma1, a, Yong Zhang2,b 1School of Mechanical-Electronic Engineering, Henan University of Technology, Zhengzhou 450007, China 2School of Mechanical-Electronic Engineering, Henan University of Technology, Zhengzhou 450007, China ayy0096@163.com, bzy15890602541@qq.com@haut.edu.cn Keywords: Drum sludge hot drying.
Influence factor Abstract.
In view of the sludge drying energy consumption problems, we summary and analyze drum sludge drying equipment all aspects of the energy consumption factors, the hope can turn to improve the drum sludge drying equipment energy utilization, reduce the energy consumption.
So a lot of the organism and the sludge particles have certain adsorption and bond properties, which promote wall sticking in the process of sludge drying, and then will reduce heat transfer efficiency of sludge, hinder the evaporation of water from the sludge, which can reduce the drying speed, cause waste energy.
We can see wall sticking of different temperature from figure 2, which affect energy consumption.

%Ce; (c) extruded without Ce; (d) extruded with 0.25wt.% Ce Mechanical properties.
Two opposite factors affected the mechanical properties of brass together.
When the content of Ce was lower than 0.10wt.%, promoting hard phase precipitation played a dominant factor and led the mechanical properties of brass decreased with the increasing content of Ce.
When the content of Ce exceeded 0.10wt.%, refining grain played a dominant factor, and thus the mechanical properties increased with the increasing content of Ce.
In conclusion, the addition of Ce failed to improve the mechanical properties.

Buildings are a crucial part of our daily life, on average people spends 85 % of their time performing activities inside of buildings and therefore the quality of the indoor environment is a critical factor affecting the happiness and productivity of building users.The indoor environmental quality has a strong relationship on the thermal conditions of a space which is directly affected by the amount of heat lost or gained due to the properties of the materials used, the external environmental conditions and the inner sources of heat; In consequence, efforts have to be made to maintain proper thermal conditions by means of using natural and mechanical strategies to provide heating, cooling and ventilation.
When these factors are known, the thermal sensation for the body as a whole can be predicted by calculating the predicted mean vote (PMV) using the following formula: where: isthe Metabolic rate, .
It is the effective mechanical power; is the Clothing thermal resistance, .
The sources of heat that affect the room environmental conditions are mainly related to the amount of heat produced by the people in the space.
Air movement Conclusions Although this analysis shows the general thermal behavior during the typical operation of these particular space types, different load conditions may occur from space to space related to the use of different HVAC equipment, lighting fixtures, constructions materials, space arrangement, occupancy rates, electrical equipment, outside weather and climate factors, among other loads,which lead to major changes in thermal comfort parameters.

This improvement in structure and properties is attributed to increasing in the cooling rate during squeezing.
Higher cooling rate, especially if coupled with a prompt large undercooling as mentioned above, can cause significant improvements in the structure and mechanical properties of the castings.
Structural changes: by affecting cooling rate of the melt and its undercooling, the applied pressure causes a lot of structural changes.
In consequence, these factors can promote an improvement in mechanical properties [11].
To evaluate mechanical properties tensile tests were carried out on machined specimens having 10 mm diameter and gauge length of 50 mm using a tensile test machine with a crosshead speed of 1 mm/min, Fig. 1.
