Integrated Computational Materials Engineering (ICME) was described by the National Research Council Report (2008) as the ‘integration of materials information, captured in computational tools, with engineering product performance analysis and manufacturing-process simulation’. The purpose of ICME is for product-level material’s engineering, its means is through computational tools and its key word is ‘integrated’. Structural materials ICME demands the integration of physics-based materials models at different scales simulating different materials processing conditions, with experimental validation, hence provides the predictive capability for cost-effective process scale up and rapid engineering deployment. Although there have been several ICME success stories in the automotive industry, technological gaps still existing in explicit integration of models at different scales and for different physical processes. In this talk, two case studies on ICME of advanced high strength steels and Mg castings will be used to illustrate the communities progress to date and gaps in ICME for structural materials.
