LNG tank has extremely low operating temperature, hazardous storage medium and large capacity storage space, therefore it is necessary to carry out temperature field analysis for LNG tank under Ultra-low temperature, and the temperature of LNG tank under Ultra-low temperature is simulated based on finite element method. Firstly, the finite element model of temperature field is analyzed. Secondly, the simulation parameters of LNG tank under Ultra-low temperature are given. Finally, the simulation results are carried out, and the temperature field of LNG tank under Ultra-low temperature is obtained.

The natural frequencies of circular saws limit the operating speeds of the saws. Current industry methods of increasing natural frequency include pretensioning, where plastic deformation is induced into the saw. To better model the saw, the finite element model is compared to current software for steel saws; C-SAW, a software program that calculates frequencies for stiffened circular saws. Using C-SAW and the finite element method the results are compared and the finite element method is validated for steel saws.

Based on modal strain energy method, the paper discusses viscoelastic free layer damping sheet, establishes the finite element model of it and obtains the natural frequencies and loss factor. Then the paper calculates the loss factor of viscoelastic free layer damping structure with engineering empirical formula, and compares the result with that obtained by finite element method. By comparing the two results, it indicates that the finite element method is effective in analyzing this kind of problems.

AbstractThe paper deals with application of the finite element method in modelling and simulation of nanostructures. The finite element model is based on beam elements with stiffness properties gained from the quantum mechanics and nonlinear spring elements with force-displacement relation are gained from Morse potential. Several basic mechanical properties of structures are computed by homogenization of nanostructure, e.g. Young's modulus, Poisson's ratio. The problems connecting with geometrical parameters of nanostructures are considered and their influences to resulting homogenized quantities are mentioned.

Effective numerical technique for treatment of inclined boundary in the finite element method was introduced. Finite element method was frequently used to analyze hydraulic phenomena in the coastal zone because it can be applied to irregular and complex geometry. In this study, we introduced the way to treat the boundary condition over an inclined bottom.

Hot rolled coil after winding cooled to room temperature in the storage room often takes 4 to 5 days. The process of coil cooling sometimes produces collapse defects in industrial applications. In this research, the cooling process after coiling of Shougang Group 72AU2 hot-rolled strip steel was taken as the research material. We used finite element method (FEM) software ABAQUS to analyze the temperature field of coil after coiling. At first, a temperature field model of hot-rolled coil during cooling was established by the finite element method. The simulation results show that, the maximum temperature difference is 206°C, when the cooling-time is about 50th min. The highest temperature node was about at 44% apart from inside diameter distance position in the thickness direction, and finally moved to the node which is at 26% apart from inside diameter distance position. Temperature field calculation considered the anisotropy of the heat transfer. The temperature of each node can be obtained by this simulation, which cannot be obtained from field measurements and experiments. Thereby this research has a significant impact on further research on the causes of the contraction and collapse.
