| Abstract Scope |
Since high-strength lightweight AL-Li alloys were gained much attention recently, because of their outstanding mechanical properties, investigating the dynamic behavior, and the anisotropic response of AL-Li alloys sheets is crucial. Thus, uniaxial tensile tests were performed under quasi-static, intermediate, and high strain rate conditions. Afterward, the Johnson-Cook constitutive model was modified to consider the effects of both strain and strain rates on the strain hardening coefficient. The results obtained from the improved Johnson-Cook constitutive model are in remarkable accordance with those obtained from experimental work. Thus, the improved Johnson-Cook model can predict the flow behavior of AL-Li alloys sheets at room temperature over a wide range of strain rates. The results of the present study can efficiently be used to develop a new manufacturing route based on impact hydroforming technology (IHF) to manufacture sound thin-walled-complex shape components from high-strength lightweight AL-Li alloys sheets at room temperature. |
