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.

The paper formulated a proposed methodology to manage diminishing manufacturing sources and material shortage (DMS) with conclusions and recommendations on the subject of component obsolescence management in a military electronic support environment.
The Companies, in which there are large-scale electronic equipment systems that must be operated, are all already lacking in the question of Diminishing Manufacturing Sources and Material Shortage (DMS) in electronic systematic systems.
The DMS project is not only a design project but also a material supply project.

Talking about the case of an aircraft, the dosage of composite materials has increased from the total weight of 2% ~ 3% to 10% ~ 15%.
A large number of composite materials has been used in demanding products such as planes and spacecraft, which is attributed to their rising awareness on properties of composite material [1].
Sometimes it causes some parts dissatisfy the strength requirement and obliterates the superiority of the composite materials.
