简介
The industrial sheet metal forming process is known for being influenced by undesired effects such as springback, fracture, or wrinkling, leading to a lack of quality of the final part. Springback is a critical problem, particularly in the automotive industry where mass production is frequently used and geometric inaccuracies result in heavy economic losses. Therefore, when designing a forming process, it is mandatory to take into consideration the springback behavior of the part in order to compensate or reduce it, through the adjustment of the process parameters such as external forces or tools geometry. The aim of this work is to discuss efficient strategies to compensate springback. To this end, two different approaches are compared: the Finite Element Method Updating and the Metamodeling Optimization. These approaches can use distinct solution evaluation strategies, namely Experimental and Finite Element …
