| Abstract Scope |
Microstructure-Informed Multiscale Structural Analysis and Design Software is a sophisticated tool designed to address the impact of complex microstructures in additively manufactured (AM) metal alloys on their mechanical behavior. Integrating a suite of microstructure-informed constitutive models for metal alloys into NASA's FEAMAC/GMC platform, this tool facilitates modeling at two length scales (grain and subgrain) simultaneously using statistically equivalent representative volume elements (RVEs). The grain-scale RVE captures grain structures and crystallographic textures, while the subgrain-level RVE models subgrain features such as solidification cells. Leveraging a crystal plasticity finite element (CPFE) framework, the software requires minimal experimental data calibration. It predicts stress-strain fields at both macroscopic and microscopic levels, aiding failure analysis and design. Compatible with software like Abaqus, Ansys, and CalculiX, this tool can model behaviors of alloys such as SS 316L, Ti-6Al-4V, HEA CoCrFeMnNi, AlSi10Mg, and IN718, advancing alloy design and performance in diverse applications, including functionally gradient materials (FGM). |
