The drawbead amount, position, size and form were studied for their affects on the formability. 3 drawbead patterns with 3 different heights were examined.
Demeri [3] identified the material properties, the penetration of drawbeads and the lubrication with FEM.
At this step, the material properties, the load boundary conditions and the tool motions were defined.
They can be avoided by increasing the punch and die radius to support the flow of material into the die or by choosing the appropriate lubricants with properties to reduce the friction between the contact surfaces of the blanksheet and die.
During the design process the restraining force and the drawbead exit thickness are 2 main factors in the sheet metal forming process [9], which are results from the selection and positioning of the drawbead lines.

There are changes in material properties of concrete when compared axially loaded short columns with micro-expansive concrete filled steel tube with axially loaded short columns with common reinforced concrete and these changes will inevitably lead to the change of axially loaded short columns with micro-expansive concrete filled steel tube in performance.
Introduction Currently, mechanical properties of common concrete filled steel tube members have been more fully studied[1,2,3,4,5,6], but the research of micro-expansive concrete filled steel tube is not over.
There are changes in material properties of concrete when compared micro-expansive concrete filled steel tube with common reinforced concrete and these changes will inevitably lead to the change of mechanical properties of the specimen.
A tear of the welding seam welded pipe that on the weld seams was the weak link, it directly affects component force performance, and produce the destruction of the phenomenon of the specimen limit bearing capacity is quite low.
The micro-expansive concrete filled steel tube under the same conditions, after mixing with 10% ~ 12% expansive agent, the ultimate damage load value increase around 8%, this plus factor can be properly consider in the actual engineering design.

The objective of this study is to evaluate how the inclusions parameter, the inclusions size and their mechanical properties influence the maximum hydrostatic stress and damage value during multi-pass dry drawing.
The modified Bridgman correction factor was used in order to predict the large deformation behavior based on the result of tensile test.
In multi-pass dry wire drawing, the mechanical properties of final product are seriously affected by the wire temperature rise during deformation.

Site Monitoring on Temperature Field Distribution of Asphalt Pavement in Seasonal Frozen Soil Region MA Hong-yan1,a, FENG De-cheng1,b, JING Ru-xin1 1School of Transportation Science and Engineering, Harbin Institute of Technology, Harbin,China amhyhit@163.com, bfdcgxy@vip.sina.com Key words:Asphalt Pavement, Temperature Field, In-Site Monitoring, Seasonally Frozen Soil Region ABSTRACT: As pavement bear the comprehensive effect of environment factors at the same time, its internal temperature field distribute complicatedly and difficult to be predicted.
Asphalt mixture with viscoelastic properties exhibits different mechanical properties and damage form on different environmental conditions.
Figure 3 2011.01.13~15 The relationship between each layer structural temperature and air temperature ① The period of temperature range of middle course and upper layer middle layer are consistent, which illustrated that air temperature is the major influencing factor of road surface temperature. ② The gradient distribution of each layer temperature was differs according to different seasons.
The PG grading is determined according to the extreme temperature of local climate, so the relationship between the extreme temperature of the climate and pavement affects directly on the rationality and economy of the material selection.
Conclusion ① The temperature gradient of each structure layer has seasonal different property.

Metallographic analysis should determine the imperfection origin and decide if copper presence was the primary factor of it.
They didn’t affect the primary quality of the material but sheet handling was dangerous, Figs. 1 - 2.
Proposals for the next treatment Blast cleaning of affected surface was proposed.
This could be done because the mechanical properties of the material didn’t change radically.

Recently, impact use of alginate, a natural polysaccharide derived from the sea algae, as bioartificial matrix for cartilage formation has been appreciated due to its both biocompatible and biodegradable properties [7].
Since coralline hydroxyapatite is biocompatible and osteoconductive, the present study is aimed to combine the properties of both CHA and alginate resulting an ideal composite-gel, which will have the ability to prevent the particle mobilization and increase in their bioresorbability while retaining the osteoconductivity.
As bone mineral contains substantial amount of carbonate (5-8wt%) in the human body and its, therefore, presence in the composite-gel is advantageous because it increases the mechanical strength as well as bioactivity of the apatite phase [9, 10] and hence more osteoconduction is expected.
As solubility is highly sensitive to the structural and chemical compositions of the apatite samples, the functional composition and percent crystallinity are to be considered as essential key factors for the biodegradation.
The distribution of calcium and phosphorus significant to CHA are still present in the composite-gel without affecting the native structure, which suggest that the structural stability of the CHA in the composite-gel.

Emulsion Electrospinning: a Comparative Study on the Development of Nanofibrous Drug/Biomolecule Delivery Vehicles Chong Wang, Sze-Nga Tong, Yuk-Hang Tse, Min Wang * Department of Mechanical Engineering, The University of Hong Kong, Pokfulam Road, Hong Kong * memwang@hku.hk Keywords: electrospinning, emulsion electrospinning, drug delivery, controlled release Abstract.
Introduction In the field of tissue engineering, there is a great interest in electrospun fibrous structures as tissue engineering scaffolds due to their nanofibrous characteristics and other properties that can enhance body tissue formation [1].
TEM analysis revealed the core-shell structure of emulsion electrospun fibers, with the structure being affected by emulsion composition.
Due to the very high surface area-to-volume ratio and other properties, electrospun fibers are considered to be excellent delivery vehicles for the controlled release of drugs/biomolecules.
There are a few factors that can cause the loss of BSA during electrospinning.

The technique is useful for the studies of the dynamic tensile deformation and the fracture (fragmentation) properties of ductile metallic materials.
Understanding the fragmentation properties of solids is important to the researchers in the fields of physics, mechanics, aerospace and defense engineering.
However, the joule heating resulted from the large electric current in the ring specimen brings a remarkable temperature rise, which may change the mechanical property of the specimen being tested.
Whether electromagnetic loading or explosive loading are applied, there are two pivotal factors that prevent the wide acceptance of the techniques: the complicated experimental technique and the expensive experimental equipment.

We define a prosthetic restoration as good if biological, aesthetic and mechanical properties of the same are balanced.
It is essential to maintain the cervical enamel margin and to integrate the incisal edge to increase mechanical resistance and enable proper placement. [38] The clinical success of porcelain veneers depends upon many factors.
But in generally, most of the cases demand some kind of tooth modification for superior aesthetics, like better color change without affecting the thickness of the veneer.
