2010, Master of Science, Ohio State University, Mechanical Engineering.
The simulation of hot stamping is rather complex and challenging, and requires information about properties of die and sheet materials, heat transfer, and friction between the deforming material and the dies. A large number of researchers use different commercial codes , such as LS-Dyna, Pamstamp, Autoform, and DEFORM to conduct hot stamping simulations with various levels of success. In this study DEFORM, a commercial code widely used for the analysis of hot, cold and warm forging operations and die design has been used. This code can consider elastic and plastic deformations of the sheet material, friction, heat transfer and elastic deflections of the dies. Two part geometries have been analyzed, using information provided in the literature as well as that obtained from various companies that produce hot stamped parts. The results indicate that it is possible to predict the deformation and temperatures in the part and in the dies by considering the variation of interface heat transfer in function of interface pressure. Using this approach it is also possible to optimize the design of cooling channels in the dies. It appears that the approach, used in this study, is quite promising for use in industrial environment to optimize die and process design for hot stamping.
