Abstract
JIS 3302 grade steel sheet material has a wide range of applications in automotive industries. Any kind of sheet metal has to undergo different forming test before a real-time application. There are many forming processes are existed to check the formability of sheet materials. Among all the forming process, bending process is one of the formability tests had a drawback interms of springback. The springback behavior is a measurable quantity for any material after the test. Based on the springback nature of sheet material end product shape finalization will be done. This has a dictum for the present work on springback effect analysis of JIS 3302 steel sheet material is focused. And also, the effect of various heat treatments on springback characteristics of JIS 3302 steel sheet metal studied using experimental and numerical analysis. For the experimental work, sheet was cut with the dimensions of specimen 150 mm × 40 mm × 2 mm in three different rolling directions such as 0°, 45°, and 90° and bending test conducted on V-bending die with 90°. For the tensile testing specimens were cut as per ASTM standard in three rolling directions. The results showed that before heat treatment, the workpiece has taken more load for bending and recorded higher value of springback, whereas, the annealed workpiece has the lowest load consumption to bend and lower springback value.
