However, little development has been achieved in numerical model approach, since tires are made of composite material with rubber and cord, and thus are highly nonlinear, incompressible, anisotropic and viscoelastic, while the states of fluid are difficult to trace, and performance of road pavements varies greatly.

The modeling of the electrical behaviour of the varistors, as well as of their degradation in service, requires knowledge of the ZnO defect chemistry, and cation and anion self-diffusion experiments have been used as important tools to characterize the point defects in these materials.

A comparative study on two kinds of 3D direct capacitance imaging sensors Hua Yana, Xiukun Ningb, Yinggang Zhouc School of Information Science and Engineering, Shenyang University of Technology Shenyang 110870, China ayanhua_01@163.com, bningxiukun@163.com, c66952508@qq.com Keywords: direct 3D imaging; electrical capacitance tomography; sensors structure; sensitivity distribution; Image reconstruction Abstract.
The 3D sensitivity distribution is essentially a map of the sensor response to a short test probe of high permittivity material in a low permittivity background as it located at different x, y and z positions inside the sensor, and usually sensitivity maps are calculated by FE method [5].

Table 1 shows mechanical properties of AZ31 sheet material as a blank material.
The used model of the materials were same as illustrated in Fig. 3, case A and case B, which are prepared to examine the effects of the different stress-strain curves on cold roll forming of wrought magnesium alloy sheets.
It has been clarified that effects of different materials models affect the stress and strain distribution during forming.
