Xu at East China University of Science and Technology computed the cooling degree coefficient and heat balance in 1999 [8].
Another example is for the type when the surrounding material has a much higher thermal conductivity than the studied material.
In this case, the surrounding material imposes the boundary temperature.

Gear material is steel and the module is 2.1e+011N/m^2, what is more, the ratio of Poisson is 0.28NA.
First enter COSMOS/Works module, second select materials, and third applied materials to all, then from the library file to the selected materials, finally OK.
Absolutely it does not exceed the material's yield stress 2.914 x 103.
At the same time, it can be checked in the both tables of the selected material that the allowable stress is 478MP, so it is a reasonable design.

Study on the Response of Stud Shear Connectors Subjected to Different Loading Rate Zaigen MU, Xiangjie LI and Jubing ZHANG Department of Civil Engineering, University of Science and Technology Beijing, Beijing, China e-mail: zgmu@ces.ustb.edu.cn Keywords: Loading Rate; low-cycle fatigue; load-slip curve; fitting parameters Abstract.
On the other hand, the stud is in a adiabatic condition, so the thermal softening of metallic material occurs, it can cut down the yield strength of the stud.

The soil is simplified to 3 layers, and used Mohr-Coulomb material model, the specific parameters of each layer soil is shown in Table 2.
Simulation Results and Analysis In the ADINA simulation, at first, selecting the same materials, the same number of anchor ropes, the same time of playing anchor ropes, the same excavation steps, the different length of anchor ropes to simulate, it will get the displacement of the pile tip and the pile packing, and in order to find the law, it will be merged into a displacement curve, the result is shown in Figure 2.
In the case of the same materials, the same number of anchor ropes, the same length of anchor ropes, and the same excavation steps, the different time of playing anchor ropes, it is simulated, and the result is shown in Figure 4.
