CORROSION DETECTION AND LIFE ANALYSIS FOR AIRCRAFT STRUCTURAL INTEGRITY

THIS PROPOSAL RESPONDS TO THE USAF'S STATED NEED FOR RESEARCH TO DEVELOP A CORROSION DETECTION TECHNIQUE WHICH CAN DETECT THE ONSET OF CORROSION AND TO DEVELOP A FATIGUE LIFE ANALYSIS CAPABILITY WHICH ACCOUNTS FOR CORROSION EFFECTS. THE PROPOSED METHODOLOGY IS TO DEVELOP CORROSION KINETIC EQUATIONS WHICH CAN PREDICT THE ONSET AND PROGRESS OF CORROSION WITH HIGH CONFIDENCE, DEVELOP AN IMPROVED CORROSION DETECTION METHOD WHICH DETECTS ACTUAL CORROSION CELLS, DEVELOP A STOCHASTIC CORROSION PREDICTION MODEL WHICH USES THE KINETICS EQUATIONS AS STATE TRANSITION FUNCTIONS, AND DEVELOP A METHODOLOGY FOR MARRYING THE CORROSION PREDICTION MODEL WITH EXISTING FATIGUE LIFE ANALYSIS MODELS.
