One of the advanced high strength steel material DP1180 is widely used in automobile industry so as to satisfy lightweight demands in China mainland market in recent years. Formability and springback problems are very serious in manufacturing. To shorten die development lead time for hard material in mass production, sheet metal forming simulation and its accuracy are becoming essential. After conducting uniaxial tension, compression-tension experiment and fitting a database for real sheet, using Yoshida-Uemori material model in integrated sheet metal simulation system JSTAMP/NV, the sprinback evaluation result is improved to close with prototype result of one typical frame part. Through this study, it is found that proper material model, real material database has much influence on the simulation accuracy for DP1180 material.
