Abstract
A springback cause identification method that includes: a step wherein analysis of press forming is performed; a step wherein a springback analysis is performed on the basis of information obtained in the press forming analysis; a step wherein the shape of a press formed article obtained in the press forming analysis is divided into multiple areas; a step wherein the Young s modulus in a specified direction of any of the divided areas is changed; a step wherein a springback analysis is performed on the press formed article for which the Young s modulus has been changed; a step wherein a springback amount difference is obtained from the results of the multiple springback analyses; and a step wherein a springback cause is identified on the basis of the obtained springback amount difference.
