Abstract

Sheet metal forming processes are extremely important in the production of many different items. However, the issue of plastic instability, which frequently results in damaged goods, still exists in this industry. To solve this problem during production, it is crucial to take into account a number of factors, limiting diagram of forming. Present case, the Aluminum Alloy (AA2014) has been used to examine its formability at various temperatures (423,523 and 623K) and at strain rates (0.1 mm/s). Stretch forming was used to acquire the study’s findings, and the Nakajima test was used. The findings were evaluated using fractography investigations carried out with SEM. The outcomes demonstrated that as the temperature rose, the material’s limiting stresses became more favorable. Utilizing LS-dyna software, the simulations were carried out. The experimental findings are within the acceptability limit according to this study.
