Machine Learning–Enhanced Multiscale/Multiphysics Modeling of Spatially Tailored Materials with Multiscale Experimental Validation

Sponsor: U.S. National Science Foundation

Project No.: CMMI-2104383

Duration: Aug 15, 2021 – Aug 14, 2024

Principal Investigator: Professor Shaoping Xiao

Co Principal Investigators: Professors Caterina Lamuta and Phillip Deierling

Past and Current Graduate Students: Siamak Attarian, Arunabha Batabyal, Akram Ghaffarigharehbagh, and Mahmudul Alam Shakib

Summary: This project is developing a new computer model to design and study the mechanical behavior of metal-ceramic composites. In most traditional composites, the component distributions are constant to enhance the material properties evenly. In contrast, the metal-ceramics composites studied in this project have component distributions that vary from location to location. Therefore, engineers can design the proper composite structure with various desired material properties at different critical locations. The new computer model includes several computation algorithms at nanoscale, microscale, and macroscale, respectively. In addition, the project provides for validation of the computer model by fabricating the composite samples and testing them on different types of equipment. This project also consists of some outreach activities for undergraduate students and K-12 students.
