The formability features of sheets made of the alloy Al 8011 are examined experimentally and the results are compared with the numerical ones in this research. Through an axisymmetric finite element simulation of the Erichsen cupping test, formability characteristics were evaluated. The Erichsen cupping test was used to exam□ine the effects of several factors, including friction at the punch-sheet contact and sheet thickness. The nonlinear finite element method is used to calculate the dome height, stress, and strain values for the aluminum sheet, and the results are then compared to the numerical ones. The findings demonstrated that the Al 8011 alloy’s form□ability greatly rises with increasing sheet thickness. The formability is significantly impacted by the lubricant. The application of the finite element technique to forecast the formability of Al 8011 alloy.
