  1. Optimization of Fatigue Test Signal Compression Using the Wavelet Transform

    SBC: ATA Engineering, Inc.            Topic: N18BT029

    Traditional approaches to accelerated fatigue testing rely on heuristic methods with thresholds based mostly on experience and engineering judgment. These methods generally do not apply to the multiaxial dynamic loading situations characteristic of most aerospace applications and often result in uncharacteristic fatigue damage and failure modes during testing. To overcome the limitations of tradit ...

  2. Systematic Fatigue Test Spectrum Editing Using Wavelet Transformations

    SBC: TECHNICAL DATA ANALYSIS, INC.            Topic: N18BT029

    TDA focuses on developing a state of the art time-frequency-based fatigue spectrum editing (TF-based FSE) framework to reduce the time of fatigue computational analysis and tests. The proposed framework will address (a) through understanding of fatigue loading histories including stationary, nonstationary, linear, and non-linear spectrums, (b) developing a multi-approach TF framework for both unia ...

  5. In Situ Marine-Grade Aluminum Alloy Characterization for Sensitization Resistance and Stress Corrosion Cracking Prediction

    SBC: TECHNICAL DATA ANALYSIS, INC.            Topic: N18AT010

    The goal of this proposal is to develop a compact sensor package and monitoring protocol for detecting the degree of sensitization in 5xxx series alloys that accounts for lot-to-lot variability. 5xxx series aluminum alloys have been utilized in marine applications to reduce weight and lower the center of gravity of ships for many decades. While effective, they can become susceptible to intergranul ...

  7. Analysis of Dislocation Density, Recrystallization, and Residual Stress in 5XXX Aluminum using Laser Peening to mitigate Exfoliation Corrosion

    SBC: HEPBURN AND SONS LLC            Topic: N18AT016

    Hepburn and Sons LLC teaming with The Ohio State University, Center for Electron Microscopy and Analysis (CEMAS) propose to research and develop an innovative application of laser peening technology to mitigate exfoliation corrosion, a special type of inter-granular corrosion that occurs on the elongated grain boundaries. Strongly related, these Mg based alloys, when exposed to tensile stresses, c ...

  8. Multi-Modal Sensing of Sensitization and Stress Corrosion Cracking Susceptibility in AA5xxx Alloys

    SBC: LUNA INNOVATIONS INCORPORATED            Topic: N18AT010

    In order to travel faster, travel longer, and carry larger payloads, new Navy ships are being designed with light weight alloys and composite materials. High magnesium AA5xxx series alloys provide a high strength to weight ratio and excellent corrosion resistance, but suffer from sensitization as anodic ß precipitates (Al¬3Mg2) are form along grain boundaries due to a combination of elevated tem ...

  9. Laser Surface Melt Treatment and Galvanic Protection of 5XXX

    SBC: LUNA INNOVATIONS INCORPORATED            Topic: N18AT016

    Exfoliation corrosion of 5XXX series aluminum alloy is an issue related to the sensitization of the aluminum substrate typically occurring at end-grains. The Navy is interested in preventing this corrosion to decrease lifetime costs on Littoral Combat Ships, Ship-to-Shore Connector vessels, and Ticonderoga class ships. Luna will investigate surface modification using laser surface melt processing ...

  10. Situational Awareness for Mission Critical Ship Systems

    SBC: Advanced Systems/Supportability Engineering Technologies And Tools, Inc.            Topic: N18AT009

    Battle situations can create loss of essential ship functions and capacities such as communications, power, cooling, weapons, etc. System state restoration today is limited by state constraints imposed by the extremis conditions, resource availability, access to critical system information, and by operator proficiency and experience. The explosion of data from various interdependent sensors, each ...
