Fracture design optimization is a methodological approach and research field focused on systematically determining the optimal configuration of materials, structures, or processes to control, mitigate, or utilize fracture phenomena for desired performance outcomes. This involves investigating the complex interplay between material properties, geometry, loading conditions, and environmental factors governing fracture initiation, propagation, and arrest, typically employing computational simulations, experimental validation, and optimization algorithms to enhance structural integrity, prevent failure, or achieve specific functional objectives related to fracturing.
