AB The production of metal parts manufactured through the hydroforming process is stronglyaffected by the difficulty in predicting the elastic recovery (springback) of the material. In addition, theformation of wrinkles and crack growth should be avoided. Manual cold work is widely employedin industry to obtain the final shape of the manufactured parts. Therefore, an accurate springbackestimation is of high interest to reduce the overall time of manufacturing and also to decrease themanual rectification stage. A working procedure based on finite element simulations (FEM) wasdeveloped to estimate the elastic recovery and predict the final morphology of UNS A92024-T3aluminum alloy pieces after forming. Experimental results of real hydroformed parts were comparedwith the results obtained in simulations performed with PAM-STAMP software. The influence ofdifferent experimental parameters on the forming processes was also analyzed, such as the materialproperties, the rolling direction of sheet metal, or the hardening criteria employed to characterize theplastic region of the alloy. Results obtained in the present work show an excellent agreement betweenreal and simulated tests, the maximum morphology deviations being less than the thickness of parts(2.5 mm). FEM simulations have become a suitable and mature tool that allows the prediction of thepieces springback, a precise material characterization being required to obtain reliable results.
