In this work, a smoothed particle hydrodynamics (SPH) based model is developed to simulate the Charpy impact behavior of additively manufactured nickel-based alloy 718. The Johnson-Cook (J-C) constitutive material and damage models that describe the strain rate, temperature softening, and damage effects are used in this study. The SPH model is validated using the tensile test at a range of temperatures and strain rates. Then the SPH model is applied to simulate the Charpy impact test at various testing temperatures. The modeling results are compared against the experimental data.
