Overcoming Design Challenges with AI

The research addresses a critical challenge in aerospace component design. Currently, engineers must develop a single material composition and set of processing parameters to meet "one part-one material" constraints. This approach often leads to inefficient design trade-offs and compromises, as desired properties can be mutually exclusive 1
