STUDY OF THE CORRELATION BETWEEN SIMULATED FORMABILITY AND ESSENTIAL FORMABILITY OF COLD ROLLED SHEETS

Regression analysis method are used in the study of Regression analysis and correlation between essential formability and simulated formability of eleven furnace cold rolled sheets, based on amount of experiments. The result showed that there exist a good homologous relationship between essential formability and simulated formability. Some simulated formability related to essential formability strongly, and the coefficient of total correlation reached more than 0.95.
