Abstract Scope |
This study presents virtual material testing via crystal plasticity finite element method (CPFEM) coupling with the Marciniak-Kuczynski (MK) model to predict macroscopic mechanical behavior of aluminum alloy sheets, particularly investigating effect of microstructure on forming limit diagrams (FLD) of AA5052 aluminum alloys. Firstly, the CPFEM simulation is conducted to identify the hardening parameters for CPFEM-MK analysis of FLD. The predicted FLDs are consistent with experimental data, revealing a significant degradation of FLD as material thickness decreases. Secondly, the microstructures varied in crystallographic texture, grain shape together with grain size are fully considered in the CPFEM-MK analysis of forming limits. Results reveal a noticeably apparent influence on formability, primarily due to distinct stress-strain heterogeneities associated with the formation of local hotspots. The present study provides significant insight into the role of microstructure in localized deformation behavior and potential failure points, emphasizing the importance of microstructural control to enhance formability. |
