Investigation on punch force–displacement and thickness changes in the shallow drawing of AA2014 aluminium alloy sheets using finite element simulations

Abstract The deep drawing process stands as a pivotal manufacturing method for crafting lightweight and robust automotive components. This study delves into the draw ability traits of AA2014 forged Aluminium sheets through numerical simulation, employing finite element analysis through the PAM-STAMP 2G code to analyse elastoplastic deformation parameters. Utilizing an ideal mesh size alongside three varied levels of blank diameters and five distinct coefficients of friction, a simulation of the drawing process for a 1 mm-thick AA2014 alloy sheet has been conducted. This modelling effort aimed to ascertain maximum and minimum thickness variations, punch forces, and displacements during cup formation. Subsequently, the simulated data were compared and validated against experimental results. Notably, the finite element simulation aptly reflected the experimental outcomes, particularly in terms of changes in the punch force.
