| Abstract Scope |
Materials and structures design can now access a remarkable set of modeling and simulation tools. Capabilities are expanding rapidly for representing microstructure important to both ‘design with’ and ‘design of’ materials at disparate spatiotemporal scales. However, the definition of microstructure may vary based on the material context. Additionally, descriptors for quantifying microstructure present a large and possibly unbounded space. The scale at which the microstructure becomes a continuous macrostructure is also subject to context. Selected tools and techniques are discussed from a viewpoint motivated by two questions: i) what multiscale tools and methods are able to provide predictive capabilities and, ii) how might the methods be incorporated into an integrated computational materials engineering framework for objective and self-consistent coupling of data and simulations? We showcase an example framework for a titanium forging, and explain how the framework allows for generic description of microstructure levels unique to a particular problem space. |
