Abstract Scope The objective of this research is to model the creep behavior of nickel alloy 718 manufactured via the selective laser melting process. A finite element (FE) model with a subroutine is created for simulating the creep mechanism for 3D printed nickel alloy 718 components. Using a multi-regime Kachanov-Rabotnov creep model, the FE model is capable to simulate both the secondary and tertiary creep behaviors. A continuum damage mechanics (CDM) approach is employed by implementing a user-defined subroutine formulated to accurately capture the creep mechanisms. Using a calibration code, the material constants are calculated. Through validation study, the model developed in this work can reliably predict the creep behavior for 3D printed metals under uniaxial conditions.
