Evaluation of Bevarage Can End Forming Process Using Kolmogorov’s Fracture Criterion

Abstract:

The present study investigates the process of beverage can end forming from 5182 aluminum alloy. Stress-strain state during forming is analyzed using finite element method in PAM-Stamp 2G, and fracturing probability is evaluated based on V.L. Kolmogorov’s fracture criterion. It is established, that stress state does not provide the sufficient plasticity margin during ends forming. Blank material plasticity resource is depleted during preliminary and reverse drawing stages, defects accumulation during countersink forming is negligible. Minimum relative elongation value, responsible for fracture-free end forming, is 6% in the rolling direction.
