Of course, the specific heat capacity of the internal material is larger, the heat absorbed will be more.
It is unable to obtain the three direction of thermal conductivity directly because of the complicated materials inside the battery[4], but it can be calculated through the principle of thermal resistance:
Among of the battery thermal effect model , the 3D thermal model is the most accurate[6].In this study, we think that battery materials are uniform texture, current density is uniform and the specific heat capacity is unchanged.

Identify the design space for frame Based on the “concept design” ideas, topology optimization can provide designer the first optimized material distribution plan.
Through optimization, the volume of new frame is 1.54×106mm3, while the maximum deformation displacement reduces to 0.99 mm, the maximum bending stress drops to 34.39MPa, far less than the material allowable stress 245MPa.

For the development of computer science, the increasing application of numerical simulation has become a shortcut to control the performance of casting process.
Cleary and Monaghan proposed a method to ensure continuity of heat flux across discontinuines in material properties [5].
The essence of temperature compensation method is converting the latent heat into temperature variation which corresponds to the heat capacity of material.

An x-ray diffraction system was used to monitor and investigate the relaxation of residual stresses in Ti-6Al-4V material under low cycle fatigue (LCF) loading conditions.
Material and Specimen The material used in this study has been chosen to be a Forged ST(1700F/1h)+VA(1300F/2h) Ti-6Al-4V titanium alloy plate because of its wide use in engine components for disks and blades.
The general mechanical properties of the material are listed in Table 1.

It has been a big challenge for scientist to predict the mechanical properties of woven fabrics because of textile materials [1] are non-homogenous, discontinuous, anisotropic and deformable.
Once the relationship between textile materials (e.g., yarns) and the textile products (e.g., fabrics) can be determined, product design for textile industry can be proceeded in a more effective and efficient way.
Furthermore, the textile materials genome initiative can start to be implemented after the applicability of geometrical modeling is approved in this study.

Results showed that the melting point is -12.2 oC at the molar ratio of 3:1 (caprolactam/ammonium thiocyanate), which is much lower than raw materials.
So, it is necessary to explore new types of ILs that they can be prepared easily with low cost materials.
Recently, a series of new ILs prepared by mixing inorganic or organic salts with solid organic materials was studied [11-13], which is different from organic ILs in structure.
For every SILs, it can be seen that the melting point was much lower than that of the raw materials.
