Evaluation of Press Work on Sheet Metal

Pressed parts made of lightweight materials with poor workability, such as high tensile steel, aluminum alloys, and magnesium alloys, are essential for reducing the weight of transportation equipment. Repeatedly modifying the die to achieve a target shape not only increases costs, but also lengthens the development period. One solution currently being tried is to reduce the number of actual samples evaluated by using simulation to predict forming problems in advance. As simulation technology continues to evolve, the use of methods such as the Yoshida-Uemori Model 1), which considers a greater number of factors than previous methods, including plastic strain dependence of elasticity based on the r-value and the Bauschinger effect, has increased. Due to improvements in simulation techniques, this catalog describes various testing and evaluation methods, including new evaluation methods, considered necessary for improving simulation accuracy.
