Laser transmission welding (LTW) is a relatively new technology for joining plastic parts. This paper presents a three-dimensional (3D) transient thermal model of LTW solved with the finite element method. A lap-joint geometry was modeled for unreinforced polyamide (PA) 6 specimens. This thermal model addressed the heating and cooling stages in a laser welding process with a stationary laser beam. This paper compares the temperature distribution of a lap-joint geometry exposed to a stationary diode laser beam, obtained from 3D thermal modeling with thermal imaging observations. It is shown that the thermal model is capable of accurately predicting the temperature distribution when laser beam scattering during transmission through the polymer is included in the model. The weld dimensions obtained from the model have been compared with the experimental data and are in good agreement.

Abstract. The paper has built 3D-FEA models to simulate the electro-thermal behavior of Li-ion battery cells with Pouch Cell and Prismatic Cell by ANSYS. As for two models, the Li-ion battery system is simplified as a single equivalent battery layer (Pouch Cell) or multiple equivalent battery layers (Prismatic Cell) with the equivalent electrodes and separator. They were simulated under air cooling conditions. Simulations were compared with available battery temperature measurements. This shows that the 3D electro-thermal model applied in this study characterizes the electro-thermal behavior of the Li-ion battery cells reasonably well.

In this paper, a two-dimensional axisymmetric thermal model using finite element method (FEM) has been established for predicting the temperature distribution profile on the work piece during electro discharge machining (EDM) and obtained material removal rate (MRR) from the temperature isotherm. For prediction of MRR, the model utilizes some important features viz. size and shape of the heat source (Gaussian heat distribution), thermal properties of workpiece, amount of heat distribution among the dielectric fluid, workpiece and tool, material flushing efficiency and pulse off/on time, etc. ANSYS software was used for developing the thermal model for the single spark operation. For this investigation, AISI 304 stainless steel and tungsten carbide was used as workpiece and electrode material, respectively. A comparison study has been carried out for theoretical and experimental MRR for the effect of each process parameter viz. gap voltage, pulse on time and peak current. The temperature distribution along the radial and depth direction of the workpiece has been reported. The model was validated by comparing the theoretical MRR with the experimental MRR and found a good correlation between them.
