Summary

Spatially tailored materials, based on the concept of functionally graded materials, are composites consisting of two or more different materials. The volume fraction of each material continuously changes in space. These composites offer advantages over traditional ones due to the ability to use the predominant characteristics of the materials that make up the composites and tailor them to the conditions and environment in which they are operating. On the other hand, multiscale modeling is the use of models at different levels of resolution (in this case, the nanoscale, microscale, and macroscale) to describe a physical system. This award supports the development of an innovative multiscale method, enhanced by machine learning, to investigate the mechanics of spatially tailored materials under mechanical and thermal loading. The proposed method, if developed and validated by experimental testing, will accelerate the design of the next generation of composites for use in the automotive, aerospace, and biomedical industries. In addition, the award will support: (1) undergraduate teaching and learning in data science and engineering; (2) recruitment of female, underrepresented minority, and lesbian/gay/bisexual/transgender/queer students; and 3) outreach to K-12 students through university programs.
