Abstract
This invention provides a method, system, and computer program to visualize texture (crystal orientation distribution) heterogeneity in polycrystalline aggregate part in large length scale. This is a critical representation step for microstructure characterization, useful in effective behavior simulation, risk analysis and hotspot identification. In contrast to orientation image map where each color component represents a crystal orientation, each color in this macrotexture map represents a set of texture. Different color represent different texture and similar texture shall have similar color. This method will provide a critical tool in evaluating texture heterogeneity of components, leading to a first-hand understanding of property heterogeneity and anisotropy. For an experienced user, these maps serve the same purpose in identifying high risk locations in the investigated component as medical imaging maps do for diagnosis purpose. This method will also serve as a starting point in mesoscale simulation with meshing sensitivity based on the texture heterogeneity. It will provide a bridge between texture characterization and behavior simulation of component with texture heterogenei…
