| dc.description.abstract | Earing is defined as the formation of waviness on uppermost portion of deep drawn cup. It is one of the major defects observed during deep drawing process. The objective of the present study aims to investigate the influence of the blank-holding force (BHF) on Earing defect in the deep drawing process of cylindrical cups through finite element analysis and experimentation. For this purpose, Mechanical properties of AA6061 and low carbon steel sheets along with deep drawing tool design parameters were incorporated in the finite element modeling of deep drawing process. The finite element software (Pam-Stamp 2G) was utilized to carry out the numerical simulation of the deep drawing process. Different BHFs were applied during the deep drawing process. The simulation results showed that the best earing is observed when the BHF is 9kN for the AA6061 alloy and 20kN for the Low - Carbon steel sheet. The earing tendency and deep drawability of the low – carbon steel sheets is higher than AA6061. | en_US |
