Effect of graded materials on product design is considered and 2D and 3D of piston are carried out.
Therefore, the project is undertaking extensive material testing for a range of materials over this temperature range with different humidity and also over extended time-periods to consider the ageing of the materials.
Effect of Graded Materials on Product Design .
Indeed, the design of over-molded components very often incorporates the different material combinations to accentuate the design to the extent that designers are able to exploit the delineation of the different materials used to produce design features as well as extra functionality.

Introduction Domain patterns and their evolution during phase transition in materials are very active and intensively investigated research topics in solid state physics and materials science.
Under certain conditions, domain patterns can be observed even at macroscopic levels for the materials such as fine-grained polycrystalline NiTi shape memory alloys [1, 5, 6].

However, research on service properties of materials and equipments with BDF is quite limited, although it is very important due to the raw materials and components of BDF is complex considerably, especially BDF has high hygroscopicity, easy to absorb water from the atmosphere to generate organic acid during the storage and use lead to cause corrosion [6-12].
It is very necessary to further study on fatigue strength and fracture mechanics of BDF devices because those were affected by many factors such as raw materials, temperature and humidity and so on during practical application [17-20].

The results showed that TiO2-NTs have a very good application potential as supporting materials for noble catalysts.
Other factors such as the stabilization, the properties of the supporting materials can affect basic properties of the catalysts [15-18].
Nanotubular materials including carbon, metal sulfides and metal oxides have drawn extensive research because of their exceptional electronic and mechanical properties in comparion to bulk materials.
The TiO2-NTs modified by APS can be good supporting materials for excellent noble catalysts.

The influence of parameters, such as whether the studs are sheathed or not, sheathing materials, screws spacing and studs spacing, on the vertical bearing capacity of wall studs is analyzed.
The panhead screws No.4816 are used to joint the steel material such as the studs and tracks, while the countersunk screws No.4838 are used to joint the wallboard and steel materials.
(2)The influence of sheathing materials on ultimate bearing capacity of wall studs According to the reference [9], we can find that the CSB is different from the OSB.

Another posibility for achieving the implant is vacuum casting process, when titanium alloys or other biocompatible materials are used [3].
Biocompatible materials used for prosthesis and implants must take into account the physical and mechanical properties of bone [4, 16].
Tensile stress can damage every kind of material, while pressure causes damage only by fragile materials [5].
CNAS Order no. 268 of 23 May 2013 [8], regulates list sanitary materials that patients included in the National orthopedics can benefit.
The obtained materials are tested for mechanical properties, biocompatibility and toxicology.
