The review included tours of two laboratories: the Center for Automotive Lightweighting and the Virtual Measurement and Analysis Laboratory. This chapter first addresses the technical merit and scientific caliber of the activities in the Next-Generation Materials Measurements, Modeling, and Simulation area reviewed by the panel.

With respect to the development of advanced manufacturing tools, the opportunity exists within NIST to collaborate with industrial manufacturing research, in which focused deliveries of the constitutive materials and mechanics models are key elements of nextgeneration computational manufacturing models. The key to the success of these NIST manufacturing programs is to move into new domains, in which manufacturing addresses the needs that include advances in stamping, casting, forging, and injection molding, and services the needs of the transportation industry, including automotive, aerospace, and rail, as well as infrastructure rebuilding and construction industries.

The program is uniquely positioned to help co-develop constitutive models with links to industry and academia, targeting specific materials attributes derived through material reinvention. The program would benefit by expanding into the development of computational mechanics and computational manufacturing, and by continuing to enhance the program's communication and partnership with industry in order to identify critical technical needs and challenges.

In many instances, project or program initiation has involved industry input through organized workshops. However, in the case of the very specific area of the Materials Genome Initiative, this multiagency program is in the early stages, and it is not clear if the program is currently being constructed with sufficient industry input.

Relative to materials characterization, modeling, and simulation, existing programs have loose ties to the needs of the industry, but there is a huge potential for expanding or redirecting materials characterization measurements to specific materials systems. One excellent example is the NIST Center for Automotive Lightweighting.

Such efforts in continuous improvements to maintain top-quality manufacturing research, to ensure standardized materials measurements, and to create next-generation manufacturing processes can be measured, repeated, and implemented at various production volumes from aerospace to high-volume automotive production. The panel's tour of the Virtual Measurement and Analysis Laboratory included an example of a highly sophisticated supercomputer effort that is producing exciting results in predicting shear and particle-particle interactions in concrete (this is a collaborative effort between the ITL, MML, and EL)

manufacturing. NIST is also well qualified to expand in the development of first-principles modeling of polymeric, elastomeric, and thermoset composite materials systems, with complementary constitutive models linking fundamental mold flow models with injection molding models of plastic flow.

From page 34... ...
Elements of fundamental first-principles materials characterization, nanoscale materials development, and smart nanoscale process development can be found in the development of key materials systems. A few examples of such nanoengineered surfaces include the following: low-cost, high-volume, infrared thin-film reflective coatings for glass; engineered thin-film-based lithium-ion batteries scalable for highvolume manufacturing; unique organometallic surfaces to control corrosion, adhesion, and friction; and thermal electric devices with high ZT and non-rate-limiting interfaces.

6. NIST should take advantage of the opportunity to play an important role in the multiagency Materials Genome Initiative as the potential repository and gatekeeper of scientific data from multiple sources.
