Abstract In this study, springback behavior of 5754-O from aluminum magnesium alloys which is started to use extensively in automotive industry was investigated at 60o V shaped die. The yield point of the material was changed by performing prestrainings about 1, 3, 5, 7, 9, 11 % and the effects of these prestrainings on springback behavior of the material are investigated experimentally. Besides that these studies were analyzed by using ETA/Dynaform sheet metal forming simulation program and compared with experimental results. Results show that the prastraining does not have positive effects on springback. The results of finite element simulations are acceptable far from the experimental results.
