- Abstract
- To experimentally investigate the forming behavior of automotive high-strength steel sheets under electromagnetic pressure, three high-strength steel sheets (DP780, DP980, and CP1180) were freely formed into hemi-elliptical protrusions. The experiments were performed using a spiral flat coil and open-cavity die. Aluminum driver plates were utilized for improving the forming efficiency. The forming behavior was investigated by evaluating characteristics such as peak height, limit height, and springback angle for various charge voltages. The effect of the aluminum driver plate on the forming behavior of the high-strength steel sheet was also observed.
