Applications to the Numerical Stamping Analysis of Tailor-welded Blanks

테일러드 블랭크의 스탬핑 성형해석에 관한 연구

Tailor-welded blanks are made of two or more different blanks in thickness or material. So car body with tailor-welded blanks need not reinforcement panels. However in order to make stamping tools for tailor-welded blanks, die engineers should know about the exact position of the welding line after the part is drawn. The necessity of knowledge about the position of welding line needs forming simulation methodology as a prior step in tooling. Therefor some parts of the simulation methodology are proposed and compared with the experimental results.
