Abstract

Deep drawing is a metal forming operation used for manufacturing sheet-metal components for application in the automobile, aerospace, and packaging industries. The objective of the present work was to study the various parameters influencing the drawability of AA6082. The deep-drawing process was modeled and simulated in Ls-Dyna Pre-Post(R) V4.6.17 software. The tensile test was
performed according to the ASTM-E8M standard on AA6082-T6 material and subsequently annealed to attain higher ductility. The annealing was performed in an industrial furnace for a temperature range of 200°C–350°C and 350°C provided the best results. Further, to predict the accurate material behavior during deep drawing, Barlat-3 parameter anisotropic yield criterion was used. The material
model parameters and constants were determined by conducting a uniaxial tensile test and anisotropy test on a universal testing machine, respectively. The experimental results revealed that annealing enhanced ductility and strain hardening exponent but reduced the strength of the sheet metal. It was observed that a higher blank holding force was required with lower sheet thickness to remove
wrinkling. The nature of the load is tensile in the radial and compressive in the circumferential direction. An increase in the coefficient of friction decreased the sheet thickness in the wall section of the drawn cup. It was concluded that the limiting draw ratio increased with an increase in sheet thickness, coefficient of friction between punch and sheet, and an increase in die corner radius. The limiting draw ratio decreased with an increase in punch speed, blank holding force, friction between die and sheet, and punch radius.

Keywords: Limiting draw ratio, Barlat-3 parameter model, AA6082, LS-Dyna
