Real-time Model Updating for Structures in Shock Environments
Abstract
This project aims to enable real-time prognosis, decision-making, and reactions on the micro-second time scale for Air Force structures subjected to high-rate dynamics (e.g., shock). This will increase their mission success rates by increasing the structure’s survivability and adapting mission goals-outcomes to changing conditions. Air Force structures to benefit from this research include hard target penetrating weapon systems, hypersonic vehicles, and active blast mitigation. The key challenge is to learn the state of the structure online during a high-rate dynamic event. High-rate dynamics are uniquely characterized by 1) large uncertainties in the loads; 2) high levels of nonstationarities, and; 3) generation of unmodeled dynamics from changes in system configuration.
