Abstract:
A method of analyzing press-forming of a press-forming material including analyzing press-forming, analyzing springback and analyzing a change in shape of the press-forming material. The analyzing press-forming may include setting an initial temperature distribution for the heated press-forming material and performing a press-forming analysis by combining temperature analysis and structural analysis to obtain shape information, temperature distribution, stress distribution, and strain distribution. The analyzing springback may occur with and without consideration of contact heat transfer between a press-forming tool and the press-forming material. The method may further include modifying the temperature distribution obtained in the analyzing springback and then re-analyzing the change in shape of the press-forming material. The analyzing the change in shape may be performed until a temperature distribution in the press-forming material is within the range of ±5° C.
