Microstructure Informatics-based Structural Design

The spatial hierarchy of microstructure is a defining characteristic of composites and alloys, leading to a wide range of material properties that impact the performance of aircraft/space/nuclear structures under extreme environments. The design and development of such structures require a combination of experiments, computational modeling, and data-driven analysis that incorporates physics & microstructure-based information at multiple lengths and time scales. 


We aim to develop novel design frameworks based on real-time experimental thermo-mechanical measurements to optimize and configure the microstructure and process parameters. We use the advanced characterization and predictive capabilities developed in the lab and collaborations with other researchers to understand and engineer the structure and properties of materials for enhanced performance and multifunctional applications.

The long-term goals of this proposed project are:

  • Formulate Physics and microstructure-informed design methodologies

  • Develop Experimentally Validated Structural Design Framework

  • Design high-performance structures and materials for extreme environment
