Abstract Scope |
In this study, Charpy impact property of 3D printed 718 nickel alloys is investigated using the finite element modeling method. The Johnson-Cook constitutive material model with damage properties is implemented in an explicit finite element formulation. The temperature-dependent impact energy is calculated, and the results are qualitatively in agreement with experimental data. |
