| Abstract Scope |
A common paradigm for micromechanical modeling is to fit micromechanical parameters to reproduce macroscopic stress-strain responses. A downside of this approach is that often non-unique sets of micromechanical parameters are capable of capturing a given macroscopic response. To address this issue, the ExaAM program has gathered bulk micromechanical data for crystal plasticity model fitting as part of a larger effort to simulate laser powder bed fusion from build to final properties. In particular, lattice strain data has been collected using high-energy X-ray diffraction during in situ high-temperature compression testing of additively manufactured Inconel 625 at the Cornell High Energy Synchrotron Source. Here we describe the data collection, lattice strain results, and connections to crystal plasticity model development. |
