Abstract
Sheet metal forming is a process widely used in the manufacturing industry. There are several sheet metals forming processes are existing including stretch forming process. In the present work, stretch formability of AA6023-T6 sheet of 2 mm thickness at room temperature and annealed sheet at 400 °C has been performed. For which mechanical properties were evaluated through tensile test for all the conditions. For stretching operations, simulations were performed using limit dome height (LDH) test using PAM STAMP 2G software. During LDH test, the maximum value of LDH for annealed sheets of AA6023-T6 at 400 °C and minimum value for sheets at room temperature is observed. Uniform thickness distribution for annealed blanks at 400 °C is observed compared to room temperature. The room temperature stretch formability of AA6023-T6 alloy sheet has 39.5 maximum dome height and annealed sheet at 400 °C has 43 maximum dome heights. By which, annealed AA6023-T6 sheet has good stretch formability compared to room temperature stretch formability.
