Development of Atomistically-Informed Peridynamics Framework for Corrosion Fatigue Damage Prediction
Corrosion related damage is a major challenge in aging naval fleet and infrastructure, adversely affecting operational safety and ownership costs. The developed corrosion modeling software provides a multi-scale computational framework to predict corrosion damage and fatigue phenomena in response to environmental conditions and mechanical loading cycles. The meshless peridynamics approach naturally allows modeling of cracks and other singularities. By providing a numerical means to evaluate the airworthiness of aircraft and to facilitate timely checks and maintenance, the framework will improve aging fleet lifetime. Targeted platforms include tilt-rotor aircraft V-22 and rotorcraft H-60 and other fixed and rotary wing aircrafts and aging Navy infrastructure in several platforms. We are seeking government and prime contractor partnerships to validate our tool and approach for a host of defense systems, alloys and corrosive environments.
Affordable, Scalable, Ocean Energy Harvesting System
Advanced Cooling Technologies, Inc. (ACT), a premier thermal management solutions provider, has developed a system to generate electricity for Unmanned Underwater Vehicles (UUV) from ocean temperature gradients. Heat extracted from warm waters is stored on-board in phase change materials to provide a continuous energy source. Integrated into UUVs or scaled up for applications such as a UUV charging station, this environmental energy harvesting system provides a competitive advantage as a renewable power source, extending UUV mission duration, improving life cycle costs, or increasing operational capabilities for UUV mission planners. After a successful prototype demonstration, ACT is currently optimizing and scaling up our innovative ocean energy harvesting system. ACT’s goal for transition is to license our technology to a prime UUV contractor and manufacture key components.
