摘要
In present investigation a methodology to determine admissible blank-holder forces in deep-drawing operations was established. According to this methodology, the deep-drawing operation is simulated and the maximum blank-holder forces, for stamping friction stir welded tailored blanks, are established based on the comparison of the numerical principal strains fields, obtained in the numerical simulations, with the limiting strains determined analytically for both base materials. Supporting experiments were performed and its results used to confirm the quality of the numerical predictions.
