Evaluation of Temperature Effects on Forming Limit Diagrams of AA6061-T6 Considering the Marciniak and Kuczynski Model

CODEN: JTEVAB

Abstract

In this study, forming limit diagrams (FLDs) of AA6061-T6 have been determined numerically and experimentally at room and elevated temperatures. The computational method has been based on the Marciniak and Kuczynski (M-K) model in conjunction with the Johnson-Cook (J-C) constitutive model. In the present numerical approach, four nonlinear equations have been solved simultaneously via the Quasi-Newton Technique. Moreover, the effects of temperature on formability have been discussed. To verify the theoretical results, out-of-plane Nakazima tests have been performed at the same temperatures, and a good match between the present numerical approach and experimental data has been seen. Both the experimental and numerical results illustrated that as the temperature increased, the FLD moved upward.
